As RDZ said, the reason why we have to keep our models in ms3d if we want to edit something in the future. I've seen the following things about importing: Milkshape crashes if it tries to import some models with the skins so you have to import without the textures, you may have to uncheck more than the textures on the importing window that appears, it is like Milkshape can only import models without the textures and the animations and it won't crash. Also there are models with the meshes even if you don't upload the textures, errors occur and 'Cannot import' message. But Mshape is an excellent program I use it too. It looks to me more accurate and easy to learn than 3ds max and not with balls for spheres etc
