Hello! I've been using ipisoft for a few weeks for motion capture and I've been very pleasantly surpised at how intuitive and straightforward the process has been.

I wanted to build a custom rig, since the ones ipi mocap studio can export don't quite match my needs. Namely, I needed to acommodate longer limbs, slightly change the column curvature, and add a few extra bones for clothing physics. But when I went to edit mode, the rig looked like this:



If I do "fix" the armature and set it so it properly resembles the resting T pose so I can work with it, then the rig breaks when trying to import it to ipi mocap studio: appendages looking at opposite directions no matter the orientation, the character being below ground, etc.

The solution I guess would be to export the animation with a default rig, then to retarget it to the desired rig with whichever editing software. But I'm afraid in the future I may want to use different armature inside ipi studio, and I'll be facing the same problem. Does anyone have a workaround, or any advice at all? Much appreciated.

Hi,
based on what you say the issue may be caused by difference in coordinate systems.
First, when you import your rig, initial frame should contain T-Pose. In this case auto-detection of coordinate system may be possible.
Also, there are "Orientation" control in a Motion Transfer Profile section of Target Character tab.
You can try to use "Auto" button to auto-detect coordinate systems, or change asix directions manually.
If none of this help, there may be some incompatibility as we only have basic built-in motion transfer features.
Specialized motion transfer software should be used for more complicated rigs.
