Hi,
I tried to bake a simple scene with a plane, cylinder and point light. I was running on an RTX project and I increased the Source Radius to make the source softer.
This is the baking result:
- I checked the uvs and they are fine
- The smoothing groups are ok
- And the lightmap res of both objects is set to 1024px
It’s strange because when I use Luoshuang’s GPULightmass on UE 4.26 dev-rendering this artifact is not showing but in this case I used the standard baking system of unreal.
In this case it was baked with GPU Lightmass, how you can see the result is much better but i’m getting Faceting on smoothing groups I guess because the resolution of cylinder it was really high, if I set it to 64px the faceting will disappear but i will get edge bleeding.
