Setup
My rigged whale has a IK-chain with dynamics to the fin, so the fin follows the upper-body movement with a little delay.
This works wonderfully so far
Problem
I animated the upper body with keyframes. Right now, IK-dynamics are recalculated every time I scrub in the timeline, which is slow.
Also, I can't resume renders, because the IK-dynamics are solved a little differently each time, so I need to cache before rendering
Question
How do I cache the IK dynamics of the fin?
For the life of me, I can't find no way to do that?!
