Hey, guys.
'Nother problem.
So I edited the VX Male Teen (http://newpowerinc.com/meshworks/ (http://newpowerinc.com/meshworks/)) and skinned 'im (he is using the keyframes that came with him).
I finally got 'im into the Character Creator and gave him powers. But! Then, when I tried to make him fight in the Rumble Room, he was flying around pink. His keyframes worked, and everything else about him seemed fine, but his skin wasn't showing up.
What'd I do wrong this time?
SOLVED!
Advanced troubleshooting, for the win.
