Hi, I have a problem with tracking is often strongly arched back and forth moves the pelvis back (although this is not the video) and it spoils the whole animation

We continue to work on improving our tracking model to behave more correctly in anatomical sense. It would be very helpful if you can share with us one of your problem videos (along with the scene file), so we can experiment with it.

I don't understand your post entirely?

I have an issue with the hips. The hips barely move. An example would be a roll sequence and when the actor puts his legs in when his rolling, the hips just stay in the same position or barely move and it just frustrates me when i have to go in Max to clean it up. Can you make it done auto like how feet touch the floor and the toes bend which requires only calculation rather then tracking?
