Sorry for the late reply, I was out of town. I’ll just explain what I am trying to accomplish: I have finally received the VRFree gloves I kick started about half a year ago, and want to use the finger data on those gloves to drive the mannequins hands in real time for motion capture. There are two things I need to do to make it work. One: The tracking solution for the gloves position is an inside out camera that is attached to the headset, but it is not accurate and I want to replace it by just ignoring it and using a Vive tracker on my hand instead. Two: I need to use the finger data to actually drive the fingers of the mannequin. My idea to accomplish this, is to use the SteamVR plugin they developed for the new SteamVR Input System, to drive the hands, as you already made an update for the Knuckles, I believe it should work like that. However, from my preliminary tests, the gloves don’t seem to show up in the scene at all when I start the project. They also have a an Unreal SDK I can use, but I have failed to get project to even open. As to my question about binding keys to the menu- I won’t be holding controllers when I am using the gloves, so I can’t use the menu to go through the calibration process and start the recordings and whatnot, so I am asking if I can have those set to keybinds. I have tried to do it myself, but I am afraid most of these blueprints are way over my head. I am familiar enough with Unreal on the using it for level building and whatnot, but I have very limited scripting experience.

Ok, got it. It should work via the project from this post: https://forums.unrealengine.com/unreal-engine/marketplace/1377349-vive-mocap-kit-support/page16
Just download SteamVR Input plugin from the Marketplace before you open it.

If you can get access to fingers animation data (curls and splays) form you gloves directly, you wouldn’t need to stream this data through SteamVR.

As for input, yes, of course you can bind additional keys to control calibration from keyboard.
