Animation/pose ?? not the same every time.

Hi, I'm kinda new to animation and pose and I'm having a problem I can't figure out.

Not all but some animation and poses I upload seem to not do the same thing every time.

Example: I made a lounge chair with a pose I uploaded. I may sit on the chair a few times in a row and the pose works fine, then sit again and have a leg moved way to the right, the next time I sit, the leg/legs have moved to yet another position. I may sit 10 more times and the legs are all over the place, and the next time, the pose is correct again.

What am I doing wrong? Thanks for any help!

p.s. I should add I have the same problem at all priority settings.

From your example it sounds like you might need to up the priority of the sit animation. Or you might need to make sure the joints move from your first frame pose.

Right: take a careful look at the sticky thread at the top of this forum, which explains this stuff. Yup, there's a bit to wade through, but it will save you a lot of frustration pretty quickly.

Do you definitely have keys for ALL the joints , that are different enough, on the second frame from the first frame? This sounds an awfully lot like this recent thread, where there are more details:
