Black Artifacts on Simple Mesh after building Light.

Hi Everyone!

I’ve a small mesh that you can see in the picture, however when I build the lighting black spots appear on the mesh. Here are some information about it:

• The object is modelled in Blender and exported as .fbx
• Object is made from quads.
• Object has 2 UV channels. (UV + Lightmap)
• Material has only base color set to white.
• Tried changing lightmap settings, all the way from 64 to 1024.
• FBX File:

I’ve provided screenshots of the problem with lightmass settings. Waiting for helping hands! :slight_smile:


Were you able to resolve the issue?
