WebXR Hand Tracking: Hands aren't positioned correctly when XRCamera is parented to a Mesh/TransformNode

[Keslinger]

Howdy.

I’m using WebXR and have a shuttle model, exported from Blender. I’m parenting the XRCamera to a TransformNode within the shuttle mesh. So far, so good. I move the shuttle around and the XRCamera stays within the cockpit. The problem I’m encountering is with the controllers (Quest 3). When I use the actual controllers, they stay in view. But if I use hand tracking, the hand models don’t track to the headset position like the controllers do. They seem to ignore the parent offset (maybe local only?). I tried one of your previous playgrounds to verify this, and I’m seeing the same behavior. Is there something I should be doing instead when using handtracking and parenting the XRCamera to a mesh/TransformNode?

Thanks!

How do you update the WebXR camera if inside a moving elevator/space ship/car?

There are several scenarios where I would like to update a player’s position when they are in or on another mesh. For example a player steps onto an elevator platform, presses a button and then is lifted up with the platform. Or several players are on a ship and when the ship’s position is translated, all the riders move relative to the boat. This resembles a classic parenting issue where the child is the webxr camera and the players can still teleport around on the ship but wherever the shi…
