It is possiable through the vive controller button control the HandJoint???

[zxzkf1992]

Describe the problem

I would like to ask if there is an API to modify the pose data of the hand model through the vive controller button? For example, by default, pressing the trigger button of the vive controller will move all fingers except the thumb to the palm. I want to modify this relationship, but I can't find the API between vive controller input and HandJoint. If anyone has done related content, or knows the API, please let me know, thanks !

@keveleigh, are these OpenXR joints or SteamVR-proprietary joints or what?

[keveleigh]

Hmm...assuming this is from the OpenXR APIs, the only way I'm aware of the influence the joints is via the hand joint motion range API https://registry.khronos.org/OpenXR/specs/1.0/man/html/XrHandJointsMotionRangeEXT.html.

I actually just merged a PR in the Mixed Reality OpenXR Plugin to add support for this extension, and the API should ship in the 1.5.0 release of that package.

If you're looking for more control, there may be something that could be hooked up with our simulated hand poses, but I believe the hand joints you're seeing here are coming from the SteamVR runtime itself.

Closing as 1.5.0 is imminent!
