Hello, When Din3D importer creates Standard materials with Diffuse maps, on Diffuse map bitmap’s “coordinates” -panel, there are tiling and rotation settings applied. Usually these parameters are not recoqnized by most exporters for 3dsmax. Problem with UV coordinates is visible when objects using materials with this kind of mapping are exported and brought to game engines for example. We would be using Unity3D to display our models. Applying the mapping coordinates directly to the object UV channel ensures that UV coordinates will be exported correctly. Could this apporoach be used in Din3D? Best regards, Jukka
