[RELEASED] for UE4: Complete Sky and Weather System

[Chosker]

btw , how did you make the clouds move? I tried the Wind param but it only makes them shift in-place but they don’t move like yours do

[Sitrec]

After updating to 4.11 (using the latest on Github) I noticed a much larger performance loss when using it. Without changing any settings or anything we now loose about 25-30 fps to , back in 4.10 without using any other settings it cost us about 5 or so. Any idea why might be?

It shows the sky, with two (potentially three) issues.

First off, when I try to open up my sequence to edit it I get :

Weirdly enough the editor does start up after that, but my licence key has expired so I can’t edit my sky. However, I can’t seem to scrub it either ( might be working as intended).

Lastly, again possibly working as intended, the god rays from the sun going through the sky extend all the way below the horizon. is probably a non-issue once I actually have terrain blocking the view but 's how it looks like nonetheless:

Edit: Add one more to it, the sky is being shown in non-level viewports (material editor, blueprint editor etc.). I could have sworn was handled a while ago.

Edit 2: The sunset is broken. I am not sure if would be visible with a terrain blocking the view below the horizon:

Edit 3: There’s a pretty serious series of bugs (maybe related to the same thing) where, if I get the time just right, both the sun and moonlight will drop down to black, making everything black. I scrubbed the time forward a day or two more and I get a moment where first my environment turns red, then the whole screen turns red. I made a video:

The moment the moonlight turns black is ~3.15 in normalized time. I can send you the sequence with the precise times if you want.

Today I got my evaluation for and I’m loving it so far.

But I have some problems as well, some like .

• I also got the same Qt5Core.dll error but after pressing OK everything seemed to work.
• The sunset is also broken for me. those black lines going towards the sun are visible and my terrain doesn’t fully block them, and they flicker so they are very noticeable. Disabling god rays didn’t fix it either. They appear ingame as well.
• The sky shows up in static mesh viewer, etc. Which is annoying

Besides that it’s a great plugin and I’m thankful it comes as a standard UE4 plugin now (I really didn’t want to mess with a custom branch or building the plugin), so I’ll most definately buy it for my project at some point

Hi, we will look into these issues for you both.

Thank you for your patience

Hi,

I will have a look into for you.

I’m wondering if some of the other reported issues could be causing frame rate problems, so can I ask if you are having any other noticeable problems (e.g. the ones mentioned by the above users) or is it just the performance drop?

I also get the error described by when trying to edit the sequencer. I’m not sure if I get any of the other things he described, I’ll check when I get a . It seems like the fps drop is as high as 40 frames, used to be just 5-10 and I haven’t touched the sequencer or any settings since switching to 4.11

when the source code for 4.11.1 ?

With regards to the Qt5Core.dll error, could anyone affected let me know what files you see in the following folder: Engine\Binaries\ThirdParty\Simul\Win64. Additionally can I ask how you all installed the latest version – was it through the repo or through the installer on the Simul website?

Unfortunately there’s not too much we can do about the of rendering in non-level viewports. We are aware of and has spoken to Epic but quite simply, the engine doesn’t currently provide what we need to differentiate adequately between viewports when inserting into the pipeline. So it could be a while until is fixed; hopefully it doesn’t cause anyone too much inconvenience.

As for any other issues mentioned, we are working on them.

Thanks

's my folder, installed via repo, merged your 4.11 branch into my own repo back when I first reported the.

Regarding the viewport differentiation… you guys just need a way for the viewport to tell you if it’s the main game viewport? What class is the viewport that you use, I might be able to whip up a pull request for Epic.

Best regards,

Hi,

That is very odd – you clearly have the dll. In our experience these errors will usually just go away with future editions so we’ll probably have to put below some higher priority issues, as it doesn’t seem to be causing anything major (missing dll should stop you from opening the sequencer, so if you’re still able to open the sequencer then it won’t be causing any other problems).

As for the pull request, I have PM’d you!

Thanks

[Chosker]

from my side about the dll error:
I installed from the plugin installer from the Simul website
I will show you my files on the folder later today when I get home

but I agree is just a small annoyance and other things are more important to have fixed

cheers

[Sitrec]

I installed in the same way as .
Do you think error might be behind the sudden bad frame rate? It’s way too performance heavy right now.

I would suspect you also have the dll so I wouldn’t worry about posting a screen or anything

Almost certainly not. It should only stop the sequencer from loading but as it does load I wouldn’t worry about that error.

We are looking into the frame rate issues though. If possible it’d be interesting to know if you get these problems in UE4.10 using the current 4.10 version as it could be that it wasn’t the switch from 4.10 to 4.11 specifically, but rather that to use the 4.11 branch you’ve updated to a more recent version of (in which the problem actually is)? However I understand if that’s a bit of a pain for you to test.

EDIT: I have been testing and I am noticing a frame rate difference between 4.10 and 4.11, but more in the region of 10-15fps. Regardless that’s not great so we will try and figure out what’s caused !

I use version UE 4.11.1 and the plugin UE4 Plugin _4.11.0_4.0.3.337.
is my problem: after compiling the game in full screen resolution of 1920x1080 the water becomes invisible.

Thank you. I think we used a slightly outdated version back in 4.10. I might be able to test it if I have time but it might take a while.

If it helps I’m using a GTX 980 TI and is what I get at about 1080p in editor and in the same part of the map:

happens to me as well. Although It did happen back in 4.10 as well and in the editor, I haven’t tried compiling and it happens both in full screen and not.

I think I know of a workaround for . Set your game resolution to 99% or 101%. I think it affects all transparent materials.

Hi,

What water systems are you both using?

And do the water materials in question alter opacity (in their blueprints)?

If possible it might be worth giving the profiler a go. will provide detailed output on the processes in . You can enable it as an overlay or more usefully, in blueprint use the GetProfilingText function (you’ll want to set CPU/GPU levels to at least 7) and print to your output log. is useful for comparing between the two versions to see where any decrease in computational efficiency is coming from. Again though I understand if that’s a bit of a pain, I just thought I’d make you aware of in case you weren’t already.

Using OceanProject as water. It reads the opacity value in BP, but it doesnt alter it, as I can see. Water working fine in editor and in my minimap, but not in the landscape as you see on the screenshot.

Try using the trueSKYTransparencyModifier function in the material’s blueprint, as explained (under Transparency).

should generally be done with transparent materials, but I know we have issues at the moment with certain transparent water systems, so if it doesn’t help then let me know.

Hey ,

I got the PM, haven’t had time to dig through the code yet. Giving it a shot as we speak.

[anonymous_user_0815e0af]

I have problem with sequencer. I can’t start sequencer GUI on 3 different computers. is installed with installer from your website. I’m using 4.11.1 UE4 version.
When I’m double click on sequencer asset nothing happens and in UE4 Output window I get error: Failed to load …/…/…/Engine/Binaries/ThirdParty/Simul/Win64/TrueSkyUI_MD.dll for ui.
