it might be how PMD/PMX editor works for editing models in Miku Miku Dance, the location of the transparent items may need to be at the bottom of the mesh/material's list to render anything behind them. but i thought more advance programs like blender bypass that problem. an second head? i know of second hands, but only reason i think may be for a transparancy or something like muscles. when i did a Delorean, it had a second fullbody mesh that later found out it was for shaders and the ice textures, but just a guess.
