I have this little interior scene I’m working on. The problem is, if I apply a normal map to my columns, their shading gets all messed up.
I tested the exact same mesh and normal map in Unity and Blender as well, no problems in either of those. Same with Substance Painter. In fact, the normal map is a SP default.
I have probably checked and unchecked every option I could find in Mesh and Material editors, to no avail. Tested with both static and dynamic lighting as well. Same with smooth and flat shading, no result.
The column itself is a simple cube mesh that I first scaled up in Z and added bevel and loop cuts to later on. I actually made this scene two times so far. First time the columns had to back faces, as they wouldn’t be rendered anyway. Thought that could be the problem, The ones in the pictures have their back faces intact.
I get no errors when importing them into UE4. I think it’s the bright columns that are getting lit up, rather than the dark ones getting shadowed.
