Hello ! How are you ?
I’ve one question if someone can help me 
I’m in webxr and I want to move the user on the vr mode. I think that when the user is moving with the three.js file it do this alone. But I think the scale is too huge I don’t know but I’v the impression that the user didn’t move. If someone know how to do moving user when he move in a room ?
I’m afraid this section is hard to understand. Can you maybe rephrase your question and describe your current and expected result in more detail?
It’s ok I’ve found the solution ! If you want to move the User you just have to go on three.js and change view.transform.matrix[12] and view.transform.matrix[14] for z axies
