Ok, sorry, by bad. Lets go from the beginning
I am trying to make a piece of apparel to cover the whole body. So for example currently we have marine armor and marine armor helmet. I want to make a single marine armor item that would cover both head and torso. But when trying to do that i found a problem. If take the piece that covers the body and glue the helmet texture on top it won't work because head texture is drawn in a higher layer than bodyarmor. The game knows what height to draw the texture on dependent on the layers that your armor covers. So if you use "Shell" layer it will draw the texture lower than the head and if you use "Overhead" layer it will draw it above the head. But there is another thing to consider. When you make a normal piece of apparel the game looks for textures for each bodytype so fat pawns get a different texture then thin pawns. But for helmet it doesn't do that because in Pawnrenderer code it is written like that "If the layer is "Overhead" than don't use bodytype textures, else use bodytype textures". So if i add a new layer it will fall into this "else" category and will require separate texture for different bodytypes and this is a good thing. However ideally i would like my apparel use a texture that consists of 2 parts-the part that covers the body and the part that covers the head. This way they could be in different layers so the will be displayed correctly in some situations where you need to hide the helmet but not bodyarmor like for the portraits in the top part of the screen.
