#Problems with lightning (or maybe shaders?)

Hi 👋🏻

I'm having a weird problem with the lightning, although I'm not sure if the source of it is Unity or Needle.

I have an office environment in Unity that counts with two elevators. In the editor, they look like the first image. But when I make a build, the result is totally different, as seen in the second image. There are some areas that are black as hell, like elevator's door.

I'm using a material with the next seen in the third image. I thought that the problem might be that it was Autodesk interactive, so I changed to UnityGLF/PBRGraph (fourth image), but the problem persists.

Does anybody have any idea?

Unity version: 2022.3.1f1
Needle version: 3.33.0

Problems with lightning (or maybe shaders?)

Hey 👋 please do use the UnityGLF/PBRGraph shader.

can you try decreasing the metallic to 0.5?
It might be pitch black like this if you do not have any environment map (reflections)

I'll try it. I'm currently baking lights and my PC takes a long time in doing it, so I'll come back to you as it finishes 🙇🏻

Other possible cause would be incorrect/overlapping UVs on that part of the model. That could cause the lightmaps to turn it pitch black

Are you using reflection probes to light the objects in Unity? If yes: what settings do you have on the reflection probe component? We currently only support the "Custom" option (with an assigned cubemap)

I'm using Baked as the type in my reflection probes

I'm about to test it and see if it is fixed

You can bake it like this, and then switch to custom and select the cubemap that was generated next to your lightmap files 👍
