VRChat

VRChat is the most common game IBIS users play (ChilloutVR, Resonite, Blade & Sorcery, and anything else that accepts Vive-style trackers work too). A few VRChat-specific settings make full-body feel right.

In-game settings

Open VRChat → Settings → Tracking & IK:

Setting	Recommendation
User Real Height	Your actual standing height. VRChat uses this to scale your avatar; it should match the height set in SlimeVR.
Avatar Measurement	Height
Allow FullBody Tracking (FBT)	On
FBT Spine Mode	Lock Hip for most avatars (or Lock Head — never both).
FBT Locomotion Animation	Off (lets your tracking drive walking instead)
Display Calibration Visuals	On — shows the tracker gizmos while calibrating
Per-Avatar Calibration Adjustment	0.2
Calibration Range	0.20 m
FBT Tracker Model	Axis — makes it obvious which way each tracker is facing
Use Legacy IK Solving	Off
Disable Shoulder Tracking	On
Shoulder Width Compensation	On
Allow Sending Head and Wrist VR Tracking OSC Data	On if you play standalone via OSC, otherwise off

Calibrate in VRChat

Every avatar needs calibration the first time you wear it:

Wear the avatar
Hold both triggers + grips (the calibration menu pops up)
Stand in T-pose with your hands aligned to the avatar’s wrist gizmos, feet 5–10 cm apart and parallel
Confirm

You should look like yourself. If a limb is way off:

Knees bend backward → mounting is wrong on that thigh tracker, re-run Mounting Calibration
Avatar is the wrong height → fix your Real Height setting in VRChat
Feet sink into the floor → fix foot height in Body Proportions

Checking your proportions

SlimeVR can cross-check your VRChat settings: Settings → VRChat Config Warnings lists every value that disagrees with SlimeVR, and the height row should match your real height in both columns. With FBT Tracker Model set to Axis, your ankle trackers’ horizontal axis lines should sit just above the floor grid — not under it, not floating.

Reset etiquette in VRChat

Yaw-reset whenever your avatar’s facing drifts off real-world. Full reset between worlds or after long sits.

If you’re using Stay Aligned, yaw drift will be much lower and you can mostly forget about manual yaw resets.

VRChat on Quest standalone

See SteamVR & OSC for the OSC setup that gets IBIS trackers into Quest-standalone VRChat.

If your avatar’s height or floor is off on Quest, reset the headset’s floor level: Settings → Guardian → Set Floor Level, then look at the floor and touch it with the right controller so the grid sits on your real floor. Clearing the physical space history (Settings → Privacy and Safety → Device Permissions → Clear physical space history) fixes stubborn cases.

Quest settings: Guardian → Set Floor Level, confirming the floor grid with the right controller, and clearing physical space history

Common VRChat-specific gotchas

“My feet are crossing through each other” — bone proportions are off. Re-check your height and re-apply Body Proportions.
“My avatar is leaning forward” — your hip tracker is too high or rotated wrong. Check Wearing Trackers and re-run mounting calibration.
“My head moves but body doesn’t follow” — SteamVR isn’t seeing the trackers. See Trackers Not Showing in SteamVR.
