Nice for fbx, about obj the file format doesn't store creases but what I mean is the use of edge sharp as a trick because OBJ store in it the normal information for the smoothness shading like this image below, is something assimilable for the creases information inside that anyway Moi3D doesn't use in importing process. As can see in the images below these edges on the model are marked only because they are marked in the obj file format.
Anyway that aren't the right way,is only a compromise.
Anyway I'm happy with new feature in Moi3D I have the ability to convert complex hull without much works already with the v4 Thanks!
