Yes but makeup could easily be done this way if the program supported it. You could draw a layer in photoshop with color and alpha and save the layer as its own PNG. Then these could be stacked, literally by stacking Image_Map nodes one to another (via the Background parameter) thus forming identical layering as is done in Photoshop.

You could then get different makeup PNG's from different vendor's and just stack them, one node each.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
