material selection on rendering

[kpavlov]

The client requested me to change some colors in Photoshop and its pretty hard to select the same material on rendering becouse lots of shadows. I tryed to render elements with material ID ...... and lots of other elements but I just cant find any that uses same color for one material so I can select it easy.
Is there a way to do that.

switch to scanline, assign 100% self-illuminated colors to your materials (different color for each material) and then use the resulting image in Photoshop to knock out your objects.
super fast and does not suffer from normal g-buffer aliasing issues.
