Vladen, thanks again for pointing me to resources. I tried in Maya 2017, found Set Normal Angle under Mesh Display menu, kept the default 30.0 and hit Apply. I exported selected FBX and brought into UE4, same message, Smoothing Groups not found. Any thoughts?
I then downloaded MeshLab and went looking for Smooth Face Normals, closest thing I found under Filters was Normal, Curvature, and Orientations, then a long list of possibilities, most likely candidate seemed to be “Smooth normals on a point sets”. This did seem to smooth the mesh, but now I’ve lost my texture. I exported from MeshLab with color for vertices and faces checked. It created an .mtl file, but drops into UE4 with no color data.
Any further advice? I realize with version changes things change names in live in different places. Do appreciate your help.
