And I decided not to bother with the Inferno creatures (their arms also sink in), as the character bends their back too much.
I have two options: either delete this animation altogether, or, as a second option, attach a non-active model in a joyful pose. The dinosaur will be active, and the heroine will simply raise her hands for a few frames.
It's a pity that we can't extract the skeleton from the game... There would be a lot of new models now.
