ZModeler UVs not exporting correctly.

  • I'm trying to take a GTA model and port it to UnrealEngine. When I import the .yft file into ZModeler everything looks perfect, textures are lined up correctly, everything looks correct. I export to .obj, import that into UE4 but some of the parts of the model are skinned correctly and others are not. When I examine the UV's on the problem meshes they are all scrambled. Any ideas?
