VRChat IK 2.0

The head on desktop is limited to -35-45~ degrees of up/down motion from a third person view. The BetaIK does not take this limit into account, and will push the entire body forward/back once you've looked past that outside limit. Clip explains it better: https://cdn.discordapp.com/attachments/946881839400882196/969455978024173648/VRChat_2JLQUSBUdr.mp4 I used the world Full Body Calibrate for the clip, as it has a third person camera available for desktop: https://vrchat.com/home/world/wrld_a5e9ec13-36b1-4e63-ae0c-dab9023401f9

I'm sorry this is machine translation In rare cases, the new IK will have cross-eyed eyes. It happens with the same behavior as looking at a camera or someone However, this Phenomenon may appear because the View Position is embedded in the head. I have tried it only a few times since it started a new IK. I haven't seen anyone else cross-eyed, but a friend said that his own avatar had also been cross-eyed. sorry this is machine translation In the new IK, eye contact rarely occurs It happens with actions similar to watching a camera or someone However, this phenomenon may be a phenomenon that occurs because the View position has penetrated greatly into the head I've only observed it a few times since it became a new IK I've never observed anyone leaning in the eye, but my friend said that his own avatar has also taken sides

When an avatar uses a custom animation controller in the base layer for movement, and use the vrc tracking controller component to enforce head tracking and hand tracking. It will missalign the hands from the controller and the head doesn't track at all and instead is using an animation. rather than the headset orientation/position. Example video: https://gyazo.com/42f2b2592e34e66ca37f1d3ad4a043f6 in the video i show the behaviour of the new IK and the legacy IK. Specifically look at the head and the hands when moving. https://i.gyazo.com/e0d78dc6bb62276277ef3c483ae4b487.png This is what the tracking controller looks like for the avatar in the video There is an exception where the hands will resync with the controller position after 1 or two seconds. but only if the "Force Locomotion animations for 6 point tracking" option is enabled on the avatar descriptor. If it is dissabled the hands will always be desynced while moving.

See attached video. When I lock in in 11 point tracking using Lock All mode. and the hip tracker is on the side of my hip, the spine leans to one side. This is 100% repeatable across multiple different types of avatars whether they are my own or from other creators and in different body types. The issue is not present when the hip tracker is centered at the front of my body.

This is motivated by @Kung's request in this post: https://feedback.vrchat.com/vrchat-ik-20/p/in-lock-both-mode-spine-scrunching-pathologically-overbends-the-neck In general, it seems that there's a bunch of cases where one-solution-fits-all would leave at least some people disappointed with the default behaviour of IK and no option to change it outside of [redacted]. As such, it seems sensible to provide more in-depth IK options that would allow users to fine-tune it for their own preferences and avatars. Naturally, it won't hurt to clearly mark these in-depth options as "advanced" and maybe collapsed by default so that average users won't be spooked by a huge array of variety - that and defaults that work well for most users will likely be sufficiently user-friendly. One important aspect here is in-game availability. Given that these options concern IK, having to edit a config file (and maybe even restart the game) just to see their effect would be incredibly bad for usability. On top of that, this same approach can be used during open beta to let users try out different approaches and solutions and gather feedback on what works and what doesn't. Options that produce split feedback would indicate that keeping it as an actual option for release might be beneficial, as people have different preferences on that specific thing.
