- As with position constraints (see Add position targets), click on the target bone then the source bone, and then click Add rotation target.
Each rotation is listed below the Position targets and is also displayed graphically.
In general, add a rotation target for each bone in the target skeleton. If the Vicon skeleton has more bones (eg, for the spine) than the target FBX, you can safely ignore them.
If your target has more bones than the Vicon skeleton in the same body segment, you can constrain multiple target bones to the same Vicon source bone.
- The relative importance of rotation and position targets is determined by their respective weights. To adjust the weight of a target, in the target list, select the target and change the value in the Weight field. A higher weight makes the target more effective in constraining the retarget pose, at the expense of the other targets. Setting rotation weights between of 100 and 200 is recommended, to help balance the effect of the positional constraints.
Tip Understanding rotation targets
A rotation target adds a constraint to the retarget solver, so the rotation of the target joint relative to the source is preserved. The joint state is an angle-axis value, and manually editing it is not recommended.
You may want to click View Filters (at the top of the view) and clear the Constraints check box, to make it easier to see the joints.
