“This object has being overlapped”. I know this problem what’s meaning and I just solved but my question is : It’s very important? I saw a prefab mesh ( a mesh where there’s “U” of unreal) which is overlapped but the results, when I apply a material, are very good.

Hey 753 Studio -

This particular message only appears if your lightmap UVs are overlapping and those are important to change or any static light built on the mesh will have shadows be transferred where the UVs are overlapping. Your UV Channel 0 which is the default Material channel can be overlapping and in most cases probably will be depending on how you are texturing your mesh.

Thank You
