What does it mean by "Only the name gets exported"? How does it know what textures go where then if it didn't consider the textures apart of the mesh?
Because materials are stored in faces individually, not in objects.
Also, in that joint you showed, I was confused about exactly what would happen if instead of holding it parallel to the players hand, you made the joint point in a different direction.
I've never tried any other rotations but I believe rotating that joint would rotate the entire model in game. The Blockheads fingers point towards the smaller end of the bone.
Also, the larger part of the joint where I have the player hold it, would I make the larger put not touch the actual mesh to have it float in space in-game?
Please restructure your sentence.
