ok, here is a pic of what i've done so far. i still don't understand how to connect 'another' bump map. the layered shader is there but how would you open up another bump map in the hypershade and connect it to the layered shader? i understand you can drag and drop the file onto the layered shader, by making layers, but i have no clue as to how to open up 'another' bump map since when i open up the attribute editor for the skin texture and load up a bump map, i can only have the one bump map. ideally i'd like to see another bump map in the hypershade and drag and drop this also onto the layered shader.
