Can someone who uses gimp give me a run-down of what they are, and how to use them? I can't find a decent tutorial. :\
Hm...I've never really used them successfully. I don't really even know what you would use them for....However, I think I've seen Zerosun use them successfully in his movie SOTW entry. Their basically frames of c4d's I guess, but that's just an assumption.
