Problems with "rock worm"

[Statyk]

If they start the animation immediately, this means the default .dae file of theirs has an animation on it (the one you actually drop into the editor, not any .dae_anim files)... The Grunt does this. While he has a separate idle animation, his .dae model has the idle animation exported on it as well, which is why he moves when placed in the editor. WHEREAS the Brute, has an idle animation, but his .dae model has no animation, so he stands in a T-pose in the editor.

Hope this helps in understanding it in some way. I'd try taking the animation out of the default .dae file or replacing it with one you like better.
