Oddly, it behaved slightly different this time, with the Simple Color node being filled in with a fleshy reddish brown color and the bump nodes being connected on all of the limbs. The flesh color was only on the upper arms though. The rest of the limbs stayed white.

Still lots of unconnected nodes left over from the base mat pose.

Interestingly, it grabbed the correct bump map file. The color map is still empty though.
