ultimate unwrap has a wide file support. i am curious if it saves/exports animations. the feature page says, Bone editor for editing bone and animation properties.

so i'm curious... does e.g. animatedFBX->unwrap3d->animatedMDL work?

Yes it can export the animations even(well is not created for animations) can change the speed of the animation.

but It cant creates the motion, only import and export it.
