You can combine your monochrome maps.
The three color channels of a color image are independent. If you were to place bump in red, and specular in green, you'd still have a 3rd unused channel you could use for something else. If your costume is only a few colors, you could place a mask in the third channel and use it to drive a Blender or a Color_Ramp to select the actual colors.
Thus you'd only have one image for color (selector), bump, and specular. They would really be three images, but you'd only load 1.
To separate the channels, you connect the Image_Map node to a component (Comp) node. Component 0 is the red channel, 1 is green, 2 is blue. Set the color to white and connect it to your combined Image_Map. If you used the strategy I described, then Comp 0 is bump, Comp 1 is specularity, and Comp 2 is your color selector.
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)
