Subject: Character Rigging, Mocap, BVH, Constraint
We’ve created a rig which is supposed to be animated by bvh-mocap-data. Therefore, we used the typical workflow, creating a FK-rig, which can be connected to the bvh-mocap-rig by the retarget tag, and connect it with parent-constraints to the IK-master-rig, which directly animates the character.
Works so far, but unfortunately, the IK-Master-rig does not follow the bvh-rig exactly. For example, the hands often are a bit to high, and the angle between the upper and the lower arm is not correct. The retargeting from the bvh-rig to the FK-transmitter-rig works fine, but something is going wrong at the transfer of the animation from the FK-transmitter-rig to the IK-master-rig.
Can somebody give a hint what to do to get an exact transfer? Of course we could use PSR-constrains instead of parent-constrains. But the problem with that is that if you mix up bvh-data shot by two different people, the character starts growing/shrinking etc…
any suggestions will be appreciated!
thanks!
