How to disable position tracking of SteamVR

As you see, I tried to disable position tracking feature of SteamVR by this:
GEngine->HMDDevice->EnablePositionalTracking(false);

But I still can move in SteamVR room space.
How can I do to disable position tracking of SteamVR?
I mean disable player moving in room space.

Yeah, how do you do this?
I want to ignore the room-scale positional tracking so I can test some non-roomscale vr ideas out…but I only have a Vive.

Seems that no way to do that. Just have a option in SteamVR for standing.

Did you ever figure out a way to do this? We’d like to have this option to experiment with but it doesn’t seem possible.

In your camera settings disable lock to hmd and enable use controller rotation. It may be wrong, try to experiment with this 2 variables.

I don’t know why you would want to do this, but what you could do is offset the camera by its own relative location every tick. I quickly put it together and it seems to do the trick.

Camera Root is just a scene component that is parented to the camera, so we can offset its rotation easily:

It’s mostly for experimentation. I’ll give this a shot. Thanks!

a reason to do this could be in a zero-g game. you don’t want the camera following you. echo arena does this

using Sigfreud’s solution fixed this for me… i literally have a 3rd person character with the camera fixed into his head, and the problem with position tracking is that it moves where the camera is, and therefore looking at your legs will be in the wrong place, your hands will be offset … with this solution that sigfreud mentioned the vision is always centered to where the camera is supposed to be …
