    First off I just wanted to say thanks again for your encouragement F3NR1S. It’s really great to hear the game has been heading in a good direction It really is starting to come together nicely like you were saying. Hopefully I'll be able to share more tidbits too. I’m not sure when I’ll be working on the water. I do have some meshes ready for it as part of sculpting the landscape, I just haven’t imported them and tried any shaders yet. I would also like to be able to do something like this: https://www.youtube.com/watch?v=GmYx1NYdqPg, but I’m not sure if it would work with a plain mesh or if I have to use splines. If I have to use splines for all the streams, it might take a while before it would be done



    Things have been pretty busy since the last update with other things coming up, and I had some health issues that prevented me from working on things as much as I would like to, but all things considered, there is still quite a bit that got done.

    I’m also happy to say that the teleporting works, but it’s not quite done yet, so I’ll wait until the next update to share new game builds. There have been some neat things to share with the vegetation as well, but this post is so long, I’ll wait until next time to share it.



    The main thing for this update is I have been working on designing and modeling that room for teleporting to various areas. Since I'm not very good at drawing, I have to do all my concept work with the 3D models. So it took a little while, and many variations, but I think I finally arrived at a design that will be pretty nice in the end. The original design that I came up was going to be a circular room a glass dome in two pieces for the ceiling. Since the entire game is meant to be an art piece as well, I had the idea that it would be really neat to have paintings on the walls that the player would then teleport through. Here is what that original design looks like in the engine:







    The idea being that you would be able to select a place to go to, then the two dome pieces would rotate around until they arrived at the painting. After this, the painting would change from being an impressionist painting of the game, into being a live look at the level. Then you would teleport to being next to a painting, hanging on the wall in one of the buildings. So it would feel like you were actually walking into the painting. As I got to thinking about it though, I realized the building would make a really great observatory for any star type puzzles, and I probably wouldn't be able to make a better one. So I decided to try to come up with a new idea for the teleport room.


    As I was trying to come up with a concept for it, I remembered another idea I had a few months ago, that I had forgotten to write down, that I thought it would be really neat to do like an art gallery up in the clouds for the main menu. Then when the player clicked on play game, it would allow them to walk around in the art gallery, walk up to a painting, and go inside of the painting, into the main game world. I realized both the teleport room idea and that main menu idea would work well together, so this was the starting point for the new building.

    It took quite a few iterations to start getting a look that I liked, and to be honest I don't normally design fantastical types of things , but I think it could be a very pretty room in the end. While I was designing it, I kept seeing all of these things hanging from the ceiling and rotating around, almost like a chandelier or prisms hanging from the ceiling. As I started trying to go this direction, things started to come together more and more, and here is what I have so far inside the engine. Blender’s booleans helped tremendously to cut the holes in the ceiling's glass grid:




    Here is the rest of it that's in Blender still with some very basic lighting:







    The idea for the building is to have a wall of some kind in the center of the building with a shaft going to the ceiling, driving the rotations for all the gears. Then as the gears are rotating, they rotate the pieces hanging from the ceiling, which have the paintings on them, and as the player gets near a painting, the hanging wall would face the player and stop rotating. Then the painting would become the live version of itself. On the wall in the middle would be the poem from the description, kind of symbolic of it being the heart of the paintings, and the thing driving the possible story piece for each building.

    Here are some shots of how the paintings look with a live version of the painting showing the game world:






    and here is one in the game world that would be hanging on a wall in a building:





    For right now, since the project is also an experiential art piece, I’m thinking that the best thing would be to have the live version flat, like a painting, instead of like an actual portal where it looks like you’re looking through a window. If anyone else has any thoughts about that, feel free to let me know. Here is what it looks like from the side:







    I also had an idea of doing these doors along the two long walls that could be rotating at random amounts, making it feel like the wind is blowing through the building as it's up in the clouds. The other idea was to have the doors in the middle start rotating first, and gradually rotate the other doors open, almost like an accordion effect. Then have them all close again starting at the far ends and going towards the middle, almost like the building is breathing, or love flowing in and out like it talks about in the poem. I'm not sure which one to go with yet though.

    Since it's going to be up in the clouds, the whole thing has been heavily inspired by clouds, with the way they move and change, and having something like rainbows in the clouds with all of the color wheels. Right now anyway, in that image up above, it's kind of neat too that the glass frames seem to mostly disappear when you're at the other end of the hall, as though you could walk off into the clouds. As part of all of that, I was thinking of having the glass color be a bit fuzzy around the edges, kind of like a rainbow effect:





    So all in all, I now have the concept work done for two buildings and I have the teleporting all working. Hopefully I’ll be able to do more with the environment soon after the teleport room is more finished.

    Thanks for looking!

        Thanks a lot Grot13, that’s a great thing to hear! Yes, I’ll keep on working on it for as long as I’m able to. I really do believe in what the project is about, and it’s also been a tremendously fun project to work on.

          Next update is finally done! My goodness it takes a long time to setup and animate so many objects! And a very large amount of code . At least the basic room for teleporting is done though, and it should make it easier to go around the level and see things as I’m working on them. There are also new game builds to try, but just to let anyone trying it know, having the portals in it is making the game crash sometimes because of having to render everything twice. I’ll add some options for it to make it better, but for now, you may have to play it at a lower quality setting.

          Here is a video I made of everything as well:

          https://vimeo.com/239392260

          I also added my first sound effect to the game!, which is the wind for the TeleRoom.

          And there are four more spontaneous piano sessions in the game now, as well on SoundCloud here: https://soundcloud.com/user-304480598




          Here is the stuff I’ve been working on with the vegetation. I want to try to do as much experimenting as I can at this early stage, and figure out what will give the best results before I make the rest of the models.

          First thing is I’ve been working on trying to figure out how to approach the other smaller kinds of aspen trees. As I have been studying the trees more, I’m finding that the main difficulty is trying to get the verticality in the leaves and branches. It’s not really something I had thought about before, but when looking at trees you see that the branches all come out horizontally while the leaves all fall down vertically from them, and this way that the leaves come down vertically is what makes us able to see the sun’s direct light on the tree from the ground. The difficulty is you can’t really have that very well when you’re using large planes for the branches and leaves.

          From what I can tell, normally this is solved by having many different leaf planes going in random directions, but with the way you can see the branches in the winter, I don’t think that would work very well for this.

          I realized too that this is the main reason that the larger trees have such a small area where you can see the light on the leaves and can look a bit splotching sometimes, because I only have the horizontal part of the branch and need to add the vertical part of the leaves as well:



          So I’ve been trying to figure out some very low poly ways that I can get this leaf verticality that you can see the light hitting the leaf, especially for the trees that are down on the ground at eye level. And again, part of the difficulty is that the leaves have to be touching a branch, since you can see them growing from off the branch in Spring. Here are some leaf clusters that I have been working on with all of this in mind. The black lines are the shapes that the texture will be on when it goes on the tree. The top right clusters are made to go vertically on triangles for the large trees, while the other smaller clusters and branches are for the aspen saplings:


          So far I’ve been able to get something that I think should work quite well for the almost bush like saplings. It seems to have a pretty similar profile to some of the pictures I have seen. What seems to work best is to have a quad made into two triangles that would only have three or four leaves on it, then you make the edge splitting the quad in half, higher than the other two vertices, making a V. You can see this with the bottom right clusters. Then you just keep rotating them as you go along the branch. Here is how it looks: (the vertex count includes some other meshes in the view that aren't visible)




          Other thing is I was able to figure out a better way to have the leaves disappear for the fall. I had been doing it though a texture mask that had a random value for each leaf that looked like this:


          , but the problem was it was leaving bits of leaves floating in the air. So I manually assigned a color to each leaf, and now it looks like this:


          The main thing to notice is the darkest leaves are in the front and will disappear last, while the brightest are in the back and will disappear first. This way it should disappear back to front and not leave any bits of leaves around.



          Another thing with this fall transition is there are rings being left around the leaves as they disappear, and I finally figured out it was being caused by Unreal’s compression settings. You can see the large blocks it was creating here:


          I found out though that if it’s set to a normal map compression setting, it’s higher quality and doesn’t cause these:


          I haven’t tried it yet, but right now the plan is to store the mask in the Blue channel of one my Normal maps, and it should get rid of the ring around the leaves.

          So all in all, once everything is implemented, the trees, and next vegetation I work on, should look quite a bit better.

            Next update is ready and there are new game builds available here: http://www.artoflightandmotion.com/downloads !

            For this update, I’ve mainly been working on implementing the ideas I had for the seasons and teleporter options I mentioned in the previous update, and I also got my first Aspen bush/sapling done! There are a few things I’ll have to adjust with it, but for the most part, I think it turned out quite well. The SketchFab landscape in the first post has been updated too.

            Dudecon, on Blenderartists, also had a great idea for having the sunlight intensity change as the seasons change, which I was able to add on this update, and I think really adds to the atmosphere of the world. I will probably be adjusting it further as I get more things done, but at least the code is in there. I also worked on the lighting for the shadows a bit.


            There is another spontaneous piano session found here: https://soundcloud.com/user-304480598/session-9

            You can see the things I have updated below, as well as a few other more real-time things in this video:

            https://vimeo.com/244945423


            Here are some general screenshots of how things are looking:






            And here are some screenshots of things I have updated:
            Difference in sun intensity, depending on seasons and latitude:
            Notice how bright the lit areas are in summer, even though it’s the same time of day for both images.



            Trees no longer leave bits of leaves behind when the leaves fall off:







            Leaves change color at the plant’s edges first, the way they do in nature:



            After adding the verticality to the branches and leaves that I mentioned in the previous post, you can see the light hitting the leaves much better now, even when under the tree. Overall, each branch looks much fuller as well:


            I also found that having a mesh similar to what is below can help a lot for the profile at the top of the Aspen bushes. It keeps things from looking flat at the top:




            Also, here are all the final shapes I used for the bush. So far the two triangles in a V seem to look the best, so I’ll be adding more variations of those to the bush with different leaf textures on them in the future:


            Spring leaves growing:





            For the next update, I’ll mostly be working on code behind the scenes. There were some things that I had done when I was first starting out, and still learning, that I really need to fix before adding more code. I also thought I would start doing a writeup about how the season transitions work, but I don’t know how complicated it could get, or how long it might take, so no promises there . I would also like to adjust the shadows for night to transition to be darker as well.



            Strictly Unreal related:
            (
            One last thing I wanted to share is an idea I had for creating references to other blueprints in Unreal’s “Blueprint” coding system. As anyone who has worked with the blueprints knows, it can be difficult to get references to other Blueprints, especially for Widget-Actor interaction. The way I had been doing it was to create the widget in say the character blueprint, and store a reference to it there as well, but then I would have to get a reference to wherever I had created the widget if I wanted another blueprint to interact with that widget. The difficulty was that I ended up starting to have references to things scattered throughout the code, and it just wasn’t very easy to interact between Blueprints.

            The idea I had though was to have all my references stored in the Game Mode class, then if I need one of the references in another class, I can just get it from what’s stored in the Game Mode, since the game mode can be accessed anywhere. The way I did it was to have one actor class that is just used for Reference Storage. Then when this class is instanced inside of the game world, I assign all of the other actor classes that are in the game world to variables in this class, using public variables that I can set up in the editor. Then I just use a get all actors of class node in the Game Mode, and set it to get that Reference Storage class that’s inside of the level. So now the Game Mode has access to all the actors that are inside of the game world, via that Reference Storage class. I also use a get all actors of class node to get a reference to the character, since the character is only instanced after the game starts.

            Next thing is I create all the widgets in the Game Mode class as well, and store them in a variable at the beginning of the game. Then when I want to add one to the viewport, I just get the reference to the widget that is in the Game Mode.


            So now, if I need to communicate back and forth between a widget, an actor, or the character, I just cast to the game mode and get the reference stored there, and I’m able to access any actors in the game and any widgets in the game, from anywhere in the game. And I only have to look for the reference to it in a single place, instead of many references scattered all over. I don’t know if it would be considered the proper way to do it, but so far, it seems to be working out pretty well. There could be some difficulty with it if you have separate levels you are loading, but I think it might be possible to just have the Game Mode get different references for each level.
            )


            Thanks for looking!

              Hi, I really like those new features, the way leaves disappear and change color is very realistic! That's definitively something I'd like to see in my project (I want the nature side to be the most simulating possible)
              Also you ask for ideas about sound, I think it could be nice to switch beetween a music or ambient sound. Birds singing in a forest is very relaxive.

              Indeed communicating beetween blueprints can be hard sometimes, I also store a lot of variables, functions and references in the game mode class because as you said it can be accessed everywhere, but I've been advised recently to develop the multiplayer early, so maybe I'll have to store things also in the game state class.

                Thanks Grot13, I’m just glad it all seems to have worked out okay! Hopefully I’ll have the write up about the seasons done soonish. I was hoping others would be able to use the ideas in their projects as well, so that would be great if you’re able to have it in your game


                Ah, yes, bird sounds would be nice to have in there, especially as it starts to look more realistic. I forgot about adding those kinds of things to my list of things to add. It would be nice to have that for the videos too. I'll probably be able to start adding those kinds of things soon. I thought I would try adding wind and wind sounds to the trees in the next few months as well.


                I haven’t had any experience with multiplayer, but yeah, I’m sure it could be quite a challenge getting everything working right , and best done from the beginning, like you said. Here was one link I had run across and saved that I didn’t know if it would help or not. Someone talks about Game Mode and Game State in the first reply: https://www.reddit.com/r/unrealengin..._for_a_single/


                I had not seen your new post. Those puddles worked out very well! It ought to look quite nice when you have more of the environment done.

                  Next update is done! Not too much to show in this update. I’ve mainly been working on cleaning up code and getting things more organized, but there are a few things I’ve added that are new. I thought I would wait to update the game builds until the next update when there should be wind in the game. I was also able to get a good start on the explanation of how to create the seasonal transitions textures and materials. It's definitely going to be quite lengthy ​.

                  First addition is that the teleporter room is inside of it’s own level now, which loads and unloads from memory. That way it’s not taking up computer resources when the player isn’t near a teleporter. It took a while to get it working because of the way the teleporters need to be linked in the code, and since the ones in the teleport room don’t always exist if they haven’t been created yet, it was causing problems for the ones in the landscape. I finally got it all working though.



                  The biggest visible thing though is I was able to implement moon phases for all the lighting at night, both for the actual moon light and the ambient light. So the brightness of the nighttime corresponds to how much the moon is lit now. While I was working on this, there was another really interesting thing I was able to add that I hadn’t thought of before. When I was looking up information on the brightness of the moon at different phases, I ran across this article that had a graph of how bright the moon is during each phase, but also how bright it is as it gets higher in the sky: http://home.earthlink.net/%7Ekitatho...moonbright.htm

                  After seeing this, I realized I hadn’t implemented any kind of atmosphere to how bright the sun and moon are throughout the day or night. Then I realized that’s the real reason why the sun is a different intensity during the winter, because it doesn’t rise as high in the sky and the light has to travel through more of the atmosphere. So after implementing that, the intensity of the sunlight throughout the day is governed by how high it is in the sky and the intensity of the winter light behaves more like the real world now. The way I had been doing it before was according to the temperature, so the colder the average temperature was, the less bright the sun was. It worked pretty well in the end, but this other way is definitely much better and the brightness ended up being about what I had set it to before. I’ll also be able to add modifiers to the brightness according to things like humidity later down the road. All in all, adding those two things made all of the lighting quite nice, and you get much more of a sense of time of day. Here are a bunch of screenshots of the different intensities:

                  Twilight to Afternoon:









                  Intensities in Teleport Room:




                  Winter:

                  Moon at Different Heights:
                  Horizon:




                  Moon Up Higher:




                  Unreal related
                  There were a couple things on the code side of things that I thought could be helpful to someone.

                  The first one is about the skylight. It turned out to be a bit of a challenge trying to get one skylight to work for both the night and day because the skylight needs to be able to recapture the environment when the lighting is changing during sunrise and sunset and at night vs day, but at night, all it captures is black, so I had to have a way that at night I could increase the intensity to get a little bit of fill light, then lower the intensity as the sun was rising and the sky was becoming brighter. It also needs to have a different intensity at night that is based on both the moon phase and a separate calculation for the atmosphere based on the moon’s position instead of the sun. Here is the final result I arrived at:


                  Hopefully it’s fairly self explanatory for anyone used to working with blueprints. Basically it uses the sun’s Y rotation to figure out whether it’s day or night, then interpolates between the value needed for day and the value needed for night, during a certain transition phase. Although the result looks simple, getting to this point was quite difficult with all of the different factors that have to be accounted for and took a lot of trial and error.



                  The other idea is about loading streaming levels. Normally for doing things like loading a saved game, I put all the code inside of a function in the Game Mode class. Then whenever the game needs to load or save data, I just call that function, but I’m not able to do that with the streaming levels because they have a timer associated with them that can’t be used in a function. I was going to try doing it with a Macro, but they can’t be called in other Blueprints because of the way Macros work. So the idea I had was to put all the code associated with loading the level inside of the Game Mode. Then wherever the level needs to load, use a Blueprint Interface to execute the code in the Game Mode whenever the level needs to load. Here is how it looks in the Editor:



                  It really works quite well, and is almost like having a function that can be called anywhere. I realize it’s probably not the most amazing idea ​, but, because of having so many different places and ways that the Teleporting room needs to load, and needing to do it through Blueprints instead of streaming volumes, I had started having to duplicate code in various places, and having it this way really organized things nicely.






                  I think that's everything. As I had mentioned before, I thought I would try to work on wind next. Now that I have low-growing bushes that won't get much wind and tall trees that get a lot of wind, I'll be able to experiment with getting the wind intensity right for both.

                  Thanks for looking

                        Thanks a lot to you both! It really means a lot. It’s great to hear that it’s looking good so far! Sometimes I've been working on it so long that I'm not really sure how good it's actually looking in the end, so it helps to get feedback from a new pair of eyes .

                          Teleport room really does its job, it is so bright and clean. It gives a feeling of peace.
                          Great work!

                            Can't wait to see (and hear) the wind!
                            What you've done with lights is nice, do you change anything else than position and intensity for lights (things like bloom or cubemap) when day/night or season transition?

                              Exadi - That’s wonderful, and thanks! I was hoping that it would feel restful and peaceful to be in! Eventually I would like to add clouds and things to it too, like it’s a room up in the clouds.


                              Grot13 - Yeah, it’s really going to be fun to see everything come to life a bit more with the wind ! So far nothing else changes throughout the day/night and seasons, although it would be interesting to play with those to see how it changes things. I did add light shafts to the sun with this update, using the occlusion method, but that’s on constantly as well since they are calculated by how foggy it is.

                              Here is how the full Blueprint graph looks for lighting:


                              and the curve for the atmosphere multiplier that uses the sun's Y rotation for the X value:


                              The only other thing that changes is the skylight gets recaptured whenever the sun has changed it’s rotation enough in the morning or evening, in order to change the ambient colors as the transition is happening:


                              I’ve been kind of surprised how just adding a simple atmosphere calculation, and changing the ambient light with it, changes the feel so much. Adding phases to the moon light brightness really changes things too. I guess it would make sense though if that’s how it is in the real world

                              Just as a note, the sun and moon positioning are from this tutorial here: https://www.youtube.com/watch?v=n7IiVU-oBK4

                                All right, I have the next update ready. There has been quite a lot that’s happened since the last update. To borrow a bit from the Matrix, I've been following the white rabbit down the rabbit hole of audio design, or at least, it feels that way . In all seriousness though, I've really been learning a ton of new stuff about audio. Although, since I’ve had to learn so many new things, I was only able to get three pieces of audio done enough to show, one for calm wind and one for strong wind during the summer, then another strong wind for fall. Since everything is about audio in this update, there isn't much to show visually either, so this post is going to be a lot of text . I am happy to say though that the wind is going to be able to work with the seasons, so it will sound different as the seasons change. I went through all of the audio stuff I’ve been doing further down below.

                                Even though there isn’t too much new stuff, I went ahead and updated the game builds if anyone is interested in hearing what's done of the wind so far. I'll do a video of it once the trees are blowing in the wind. Since I don’t have any weather implemented yet, in order to change the wind speed, you’ll have to go to the weather tab inside of the in-game options menu, accessed by pressing the E key in-game. I also did a bit of preliminary work on getting the trees to move in the wind. It’s going to take a lot of experimenting, and it’s also all very new to me, but from what I can tell of it so far, it might be possible to get some pretty neat effects with it.

                                Also, I have the text for the first section of the write-up for how to do the seasonal changes done, but still need to add pictures. You can see the progress so far here: https://www.dropbox.com/sh/v03321o6y...B50CLCYga?dl=0 There are probably a lot of spelling errors in it still .



                                I didn’t know if anyone would be interested in this or not, but I just found out that one of the stories I had mentioned a while ago, and that is talked about in the Inspiration section, that also partly inspired the project, was put up on YouTube. So if you would like to see part of what inspired the whole project and what continues to inspire it, you can see it now. It’s a very, very old interview https://www.youtube.com/watch?v=63vM7NcrB-o



                                Now to talk a bit about the audio, the beginning of the adventure started while I was working on implementing the audio using Unreal’s audio engine. There was something I was looking up how to do, I don't remember what, but as I was searching, I ran across this tutorial on YouTube about using an external audio engine to do the audio in a game: https://www.youtube.com/watch?v=1QdDwQONq_g. From there I started looking up audio engines to see what might work best for me, or if I even needed to use one. In the end, I ended up choosing one called Fmod for it, and so far it's working out pretty well. It's definitely much better than working with Unreal's current audio engine.

                                From there, I also started looking up dedicated audio workstations to see what kind of options are out there, and I ran across one called Reaper that's a full fledged audio workstation for only $60. This is one of those things that I'm incredibly glad I ran into and bought. I had been using Audacity to try to work with the audio before, but after working with Reaper, my goodness it's incredible the kind of stuff you can do with audio. That kind of ties in with the other thing I learned about audio, that there aren’t very many places to find good audio for free out there, that will right away work with what you’re doing. One really amazing place I found worth mentioning is https://www.zapsplat.com/ ; they really have a ton of free, very high quality sounds done by audio professionals.

                                Back to my audio, so far, I’ve only been able to find one piece of audio that has the sound of aspen leaves in it, and it's only in strong wind as well: https://freesound.org/people/juskiddink/sounds/78955/. This is where having Reaper has been a huge help. I definitely wouldn't have ever been able to do what I've done so far with the wind without it. One of the biggest things that helped was having a real time equalizer, which made it possible to adjust frequencies and immediately hear what I had changed while the audio was playing. This made it possible to isolate the sound of the leaves:





                                After they were isolated, I could then layer them on top of each other to make it sound like there were more of them. Here is what it looks like for the calm wind. The leaves on the first 4 tracks are from the piece of audio mentioned above. Then the Far Off Leaves are from another audio file. The track at the top is some audio I decided to mute and not include in the final mix:





                                Since the wind sound was no longer with the leaves sound, I was also able to use other files for the wind that sounded calmer. This all gives a very large amount of control over the final sound of the wind and leaves. You can see the wind on the bottom track:





                                Reaper is also great with the way it automatically crossfades sound clips together, which makes two audio clips sound like they're one clip. This is used a lot in the Strong Wind audio and makes it easy to split a piece of audio and put the pieces wherever you want them. The crossfades are the red areas:





                                Now, about getting it all in the game, right now the plan is to have different wind sounds play for each different area type; one for aspens, one for pine tress, one for meadows, and so forth. They have such distinctive sounds that I thought it would be worth it to spend the time and create unique audio for each. In order to have all of that work, I had to create an easy way to automatically select which audio to play in a certain area, then do all the setup work for that audio, like telling it what season to start in, or what the wind speed is on each frame, and things like that. In order to do that, I also had to be able to get a reference to the audio actor in the gameworld, otherwise I can't tell it what to do. So I ended up creating a blueprint with a sphere trigger, and attached the audio actor to the blueprint:





                                Then when the player enters the sphere trigger, the sound starts playing, the setup work can be done on it, and a reference to the audio can be stored somewhere. One of the really neat things about having the sound inside the blueprint is, since I would be able to easily get a reference to every sound actor, I was able to have it be a 3D sound instead of a 2D sound played through a single, global audio actor. So as you go out of the Aspen grove and turn the player's head, the sound of leaves comes from the direction of the Aspen grove.

                                I think that's everything new for now. Congratulations if you made it through all of that text!
