We have a VR application where the user can control the light of the scene. The scene can get pretty dark. The user interface an 3D objects that are part of the interface shall not get affected by the scene lighting (VR Controllers).
We removed the elements from Lighting Channel 1 and placed them into Lighting Channel 3 and now the problems begin. I simply would add a skylight and set it to channel 3, but as skylights do not support channels, we can’t do that. I tried to setup 3 directional lights for Channel 3 but the result is still horrible. Just using emissive materials looks horrible.
I thought about using prebaked light maps (baked in e.g. blender) but materials do not support that.
Also the elements are affected by the user controllable SkyLight…
