Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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.

Product Version: UE 4.12

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. alt text

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

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
