Interesting trivia: wicker_behemoth_morph.g3d contains 10 sets of texture coordinates, and if each frame is rendered with the appropriate coordinates then the body glows with an inner fire effect.
The game engines don't seem to show this though.
Presumably it worked at some point once when the model was originally made?
(There are no other models that use this 'feature' that I have found; anybody know anything about it?)
If anyone has anywhere to host a 100KB video, I have what the effect looks like as an AVI.
