Program used to make Model and rig: 3D Max 2011 Help! I make two meshes just fine but when I tried to upload the 3rd model, the skin weights can not be checked. Is there a limit on how much vertices and traungle an avatar can have? Also, If I group anything in 3d max and try to export it, this warning pops up.
