[Community Project] WIP Weather & Ocean Water Shader

[NilsonLima]

Can i use this in my project ? , and how can i copy this without breaking the code?

Yes, you can use in your projects, it is free. You are only forbidden to modify it and resell it in source form, please check the license file attached into GitHub.

As for copying without breaking you can refer to this video, with a step-by-step. Just know that this is a C++ plugin & Blueprint asset, so you will need Microsoft Visual Studio installed to make things easier. The video:

Hi,

First off thanks to all who have contributed to this amazing project.

I've been having a lot of issues trying to get the buoyancy component to work, every time I add buoyancy to something like a simple sphere unreal engine instantly crashes. Not sure why as I can run all the example maps fine without unreal crashing. But every time I try and add buoyancy to a custom object like a basic sphere/cube unreal engine instantly crashes when you press the play button. This happens with all of the various type buoyancy components.

I can add the ocean BP to my scenes just fine with no crashes, but when adding a buoyancy component unreal just crashes on play.

It seems like it's coming from the ocean manager class and I have no idea why. I can also reproduce the crash in the example files by just adding the ocean manager class
to the level. As soon as I do that and press play unreal will hard crash.

Not sure what I'm missing I've followed the tutorials for setting it up for your own projects and didn't get any errors during the setup. I can add the buoyancy component items fine in blueprints
setup things up and compile and save the blueprints fine. But on play unreal instantly crashes.

using version 4.19.2 and the latest version of ocean project from github.

Any ideas as to what is causing the crash?

Thanks for any help.

I will check this for you, meanwhile why don't you get in touch with us by Discord. It will make life easier and the amount of ppl online there might cast some light on other issues you may encounter: https://discord.gg/qwESbbW

skywaves I would have to look if in the github history any issue related were fixed, but I have access for the wip version about to be released in few weeks targeting 4.19.2 and it is working fine. See if you are using the steps on this video (I am uploading at the moment) :

Awesome, thanks for that video. It really helped with getting things to work, when i was first attempting to add buoyancy to my objects, I was following the buoyancy tutorial from Handkor.

After doing it your way without adding the ocean manager class to the level it worked we no hard crash in unreal engine.

Many thanks again. The crashing was driving me nuts

Few post earlier I have posted another video on how to migrate the assets to another project and no need to tap with the C++ base classes, all can be correctly done with the blueprints deriving from them. Don't forget to join the Discord server with the link I provided earlier aswel (if you didnt already), other tutorials like this will be added and soon DotCam will release updates that will make this asset even better!

Great, look forward to the updates. l'll also take a look at your other video as well and join the discord.

Thanks.

Is it possible for anyone to convert this project to 4.20 Preview and share this branch ?
I tried to do it myself but I got a few errors related to Visual Studio and I've no clue how to solve this myself.
Don't bother if it's too much work. I imagine 4.20 is pretty close to being released anyway

We are working several changes into the package and we are closely testing it with 4.20. The release will be almost same time and the package will be even better, stay tunned!

Ah that's great news ! Can't wait to try it out again

Been playing around with this release for awhile and i just want to say great work! I was wondering though is it possible to make the waves smaller? I myself have not figured that out yet

[MrLamino]

Great great great job !

To make waves smaller you need to play with wavelength and amplitude settings all the way down the parameters in the BP_Ocean blueprint. Reducing the values basically can give you a calm water like a pond!

Hello,

Another buoyancy question, is it possible to get the buoyancy system to work on another type of object instead of the inbuilt ocean? For instance if I wanted to use a custom deforming mesh for an ocean instead of the inbuilt ocean. Or is the buoyancy heavily tired to the ocean? Would it mostly involve just getting the custom deforming mesh to feed the buoyancy system the height of the deformations, or is it way more involved than that?

Thanks.

The buoyancy system is tied to the ocean solution, because we need the values for the ocean plane height in order to do the math which is simple: How much is the test point below or above the water? With that you can go and apply the correct force on that test point.

If not in the ocean, you can create your own buoyancy looking at this: https://t.co/xFxkjYc3MM and look for Simple Buoyancy Physics and Simple Boat Physics template projects.
