I am wondering if i could get some tips from the wonderful people of this group. Does anybody have any experience working with CMU Mocap animation? I am currently working with bvh files.

I have a rig already setup(rig assembled by a add-on called auto-rig pro) to which i am trying match the bones of my rig to the bvh. Auto rig pro has a remapping function for bvhs which I'm using but i get errors with this. The most common is twisted limbs and jittery animation.

I'm confused about the rotation of these bones and how to fix them of if i should use ik or fk when remapping.

Also I am researching how to fix the rest pose of the bvh armature, so that the mapping of the bones would result in a better animation but that lead to errors.

I tried using @batFINGER's script for resetting poses and all the post he did so far but I'm getting nowhere or at least i don' think I'm following it right.

Can anybody help? Thank you.

First Example

Remapped using Auto Rig Pro add-on

  • $\begingroup$ My link is for two rigs with same bone structures. My bvh addon "mocap madness" which was basically targeted to CMU is a long way on the back burner. Often addons (if hosted on github for example) have an issues page. It appears the wrists may have a 90 degree roll. Consider posting a simplified blend to blend-exchange.giantcowfilms.com. Include bvh rig, target rig and say 10 to 20 frames of an action where issue occurs. Also, welcome to BSE. Upvoted (cos it's a good question, not just cos i got a mention lol. (If I've used the wrong link please change) $\endgroup$ – batFINGER Mar 23 '19 at 4:08
  • $\begingroup$ Thanks for the reply. I changed the link because i was talking about the post for just changing the rest pose. the bvh and my rig have way different structures. i tried searching on the add-on’s github page to no avail. i can send you the blend but i don’t know how much info you will get because of the auto rig add-on. The add-on I’m using is basically like the mocap remap tool that you can find on the plugin page. Everytime i remap the bones the errors happen $\endgroup$ – Dominic Keeton Mar 23 '19 at 5:23
