Extract the .rar file that Pax invictus posts in this threads into your 4.24\Engine folder. Theirs a readme in his documentation as well

I am so confused. I have a project done in Unreal Engine 4.23. What files do I need to copy for that? Can I switch between CPU and GPU build when this is done?

HI Everybody,

i still love this magic tool! It's sooo cool!! (I'm still on 4.19)

But there's one thing I can't get working right; foliage.

My flowers (create with the foliage UE tool) are "burned" a bit ...
(see attached)

And with trees I have an other issue, setting them to static leads to very dark leaves.
Setting them to stationary they don't look good...

Beside off trying several things, turning off "two-Side" in the leave material, "erases" half of the tree...
and doesn't make any difference...

All foliage assets are take from the foliage-pack.

ANY HINTS where to look at or work-around would be great!

Thanks a lot in advance.

Hi guys,

Is this gpu usage normal?

[enoes]

Best experience Game Ready Driver or Studio Driver ?

[KACPEROGO]

Hello, I post it just to share my observation. I use 4.24.3 with GPU Lightmass and had a constant problem with Lightmass crashes. The problem was with the terrain, I had some static geometry attached to it. After detaching trees and turning static shadow off it finally worked.

[christianstamati]

Hi,
does anybody have a solution to this problem? Here I'm using UE dev-rendering (4.26) and I also baked the scene using GPU Lightmass. How you can see there are some problems when I bake rounded objects. The smoothing groups are not working properly here you can find more info: https://answers.unrealengine.com/questions/956758/ue-faceted-smoothing-groups-after-baking-luoshuang.html

Yes, I confirm! This morning my computer finally compiled Unreal Engine 4.26. When VS finished building I don't know why sometimes I'm getting this error:



But It's strange because it's not my first time that I build the engine I did It 2 days ago and it was everything ok... Anyway I launched it and even if there was this error it was working...
I made quick plane and cylinder in max with uvs and smoothing groups and I tested It, the result was amazing! And since I have an RTX 2070 it took no time to render.



Settings:
- ShadowSamplePerTexel = 1024
- SampleperTexel = 1024
- PointLight (Source Radius = 40)
- Lightmap Res = 1024


I also tried increasing more the Source radius of the light (160) and I got this result with the same settings:



But I think it's ok, after I will trow a high res texture on the surface that edge will not be noticeable...

GPULightmass is really good feature it's solving a lot of problems:
- Baking Time
- Edge Bleeding
- Smoothing Groups Faceting Artifacts
- Modular Assets Baking problems ecc...

I really can't wait to see it on the official release!

[Luoshuang]

Yes, I confirm! This morning my computer finally compiled Unreal Engine 4.26.

1) Does disabling denoiser (r.GPULightmass.DenoiseGIOnCompletion=0) help with the edge problem?
2) There are advanced methods like Caching GI Engine (https://github.com/EpicGames/UnrealE...311fd423bd0163) and Ray Guiding (https://github.com/EpicGames/UnrealE...7c3636ad941556). Read the comments of the commits to see how to use them

[Stefano Longo]

Hi,

I have some problem with a scene that I have baked a lot of time but not I have this issue...
Which is the reason? It can't be a RAM problem because I've already bake this scene! I also tried to transfer the model to a new file but same error .....

Thanks!
