Hi Partel, We're using VRIK for controlling our avatar. However we want our game to be playable either with a full body-tracking (HMD + 2 controllers for hands + 3 trackers for pelvis/feets) or with basic set (HMD + 2 controllers for hands). We actually have no problem for the full body, the solver is working well. But when we remove the trackers and start moving around our scene, the avatar move and start walking but keep his legs stretched as if the avatar doesn't have knees. We tried playing with locomotions variables and make sure the position weight of pelvis/legs are to 0, but there's no change. Do you have any idea of where it could come? Thanks in advance, and good job for your asset.
