Thank you Pärtel,
The Calibration demo has helped quite a bit with setting up the trackers. Now we're able to make the Dummy model to stand relatively straight.
We're still having challenges when we use our own models. They have a bit shorter legs and arms and longer torso, so for example we have to bend our arm quite a lot before the model's arm starts bending as well. Or the model stands on tip toes while we have relaxed legs or slightly bent. Do you have anything we can try out here to get a better retargeting? Thanks!
