I am trying my hand at making a top for my CaC by combining a few different pieces into one. I've taken the models into blender and gotten them to fit together fairly well (I am by no means experienced in Blender, but I know some basics) but I am concerned about joining them together. I've used the Beerus top as the base and it has four busts layered together, the 1306_Bust and 1306_Bust_LOD01-03. Should I join all of them together or leave the LOD ones as they are? Obviously I plan on giving the end result a unique identifier but I am not sure about the joining stage.
Also, it would be nice if I could customize the colors in-game but don't know how to do so. If it is simple enough and someone would be willing to point me towards a tutorial/tell me I would be very appreciative.
