[HTC VIVE]: is it possible to lock player movement?

Hi!

I know this isn’t good and can make player sick, but is it possible to refuse player movement and leave rotation only?

Or “scale” movement in 0.5 times, for example, or even 0?

I could do this with Oculus DK2 (with set relative location of camera), but this seems not working for VIVE?

(Sure, I can try to move whole level attached to camera position, but this wouldn’t work for big level, isn’t?)

Thank you in advance!
