Are the cloth and belts a MatCap material? If so, these normally don't respond to lighting, as they're bitmaps with lighting baked in. Use regular materials instead.
Finished the Sculpt and started to do the lp and unwrap, so far body is done, accessories and clothes are next.(please excuse the artifacts on the armpits)
i thought the characters were all 3d scanned, not hand crafted really. anyways, the amount of clothing variations and the environments look impressive.
