So i have been having this issue where my mesh goes black after i build the light.
Here is what i tried
- reimport the mesh
- delete all light and use the one from the default level
- set light map resolution to 64 and light map coord index to 1
All of the above did not fix the issue
I get this warning when i build light : No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times.
this mesh is really big but all other small mesh have correct light.
Here is before
Here is after
This is my outliner
