I just created a grey bomb_cart skin so that I can attempt to create some kind of neutral payload hybrid. When you browse models some models have different skins that you select from the mdl studio - How do I add my grey skin to an existing model? just saves space rather then having an entirely new model. I plan to make a lot of skins of existing models, making sure each one has a red, blue and neutral version - being able to have additional skins would be a lot easier then having additional models. Any help would be greatly appreciated.
