Hey, guys)
Really need your help.
I have a mesh modeled in Blender and imported in 3ds max.
Basic studio setup, one physical camera, one targeted corona disc light, same CoronaPhysicalMtl on the mesh and the studio plane. 1 smoothing group used by the whole mesh.
And a shading bug I can't fix.
I've made the same setup in Blender and it looks clean. The mesh is really straight and simple.
I've tried every possible way I knew (different export/import settings, fbx/obj, reseting/unifying normals, with/without studio, etc) and it didn't help. There's nothing special about this mesh, no edge weights, no custom normals, no flipped polys, nothing. The most special about it is this bug).
I'd really appreciate your help with finding the solution.
Thank you!
