I have been trying to solve my UV(Lightmap) issues. I have some architectural geometry , which is impossible to Unwrap UV’s manually. So, i use automatic unwrapping system on 3ds Max ( Flatten Mapping ) . However with the most of my complex objects , it doesn’t work. When i import it to Unreal and build it , it keeps saying there are some overlapping UV’s and my material looks so awful on the object.
It doesn’t make any sense because flattening mapping should unwrap every single face and lay them seperately. So what’s the problem? I don’t need a manual unwrapping because most of my objects will be assigned just colors. No textures.
I want to know if anyone else is having the same issues.
