VRChat IK 2.0

This problem has been confirmed to occur since at least March 28, 2022 I have a problem with periodic loss of tracking when using the index controller with ik-beta. The tracking is lost and it continues for a while, as when you lose sight of the base station. It is relatively stable right after startup, but I have the impression that it becomes more unstable the heavier the operation is. My friends who use the INDEX controller also complain of similar conditions. -No problem on non-VRChat applications or on SteamVR. -Open-beta,Release version does not have the problem. -Controllers and trackers other than index controllers do not have this problem.

When you're wearing a chest tracker on the 'lock both' setting, hitching your hips forward causes most of my avatars' chests to pop out.

When i wear 11 point tracking, after calibration, the right foot will point 30 degrees clockwise. The left foot, registers both trackers but 90 percent of the movement of the leg's IK is controlled by the foot tracker. This error appears on 2.0 and 3.0 avatars.

TLDR: Vrchat elbow behavior is still incorrect, With 6-point tracking. I have used streaming motion-capture software that is more accurate. The information below best explains this. Check screenshots. The following is a screenshot captured from my motion capture software that I use for streaming. This software's IK system Best reflects my physical body's actual pose in physical reality. Notice where my elbows are. Notice how my forearms are parallel with my virtual body. This is a one-to-one with reality. This was captured using a six-point tracking system. The Avatar reflected here is a vrm conversion of Vrchat Avatar. The Armature of the Avatar is no different than the one that is being used in vrchat. It was converted to using {UniVRM} https://drive.google.com/file/d/1NWHFrszOCzLsI3X6GSy3IDcuHuBQJf-t/view?usp=sharing The following is a screenshot captured from vrchat. I'm using the exact same trackers (6 point) Again the Armature with the avatar is no different than the one in the previous screenshot. Notice where my elbows are and how they are not in the correct position. My forearms are at an angle and not parallel with my virtual body. My physical body is posed is the exact same as in the previous screenshot, above but VRChat doesn't reflect this. The only way I can explain why there's a difference between these two is perhaps in the IK systems that the motion capture software uses in relation to the one that vrchat is currently using in the most recent ik beta. I'd really like to see behavior like this change. This is only a small example of the desync I have experienced between physical bodies and virtual ones. There's a similar effect with knees. I don't have the time to capture every single pose and every single desync that occurs. But if I notice anything specific I can post another canny post or attach it to this one https://drive.google.com/file/d/1NSaJEzdqrB-kP8Wp3CjCqvZLI5IdOcgP/view?usp=sharing I updated the original post to be more clear.
