Howdy -- Nice looking box; I should look at architools, I think. Wouldn't have thought to use it for something like this. As for changing colors of texture in Photoshop, there's a simple process you might use. Open the image in PS, select image>adjustments>hue/saturation (or Control+U on a PC). Then adjust the hue slider (or enter numeric values). This is a large adjustment, so tiny movements on the slider are probably in order. You can also play with the lightness and saturation sliders for more variation. Not sure what you're asking about photo lineups, though. It sounds like you're wanting to do some UV mapping, which is pretty decent in C3 and up. Hope that's helpful. - Dex
