Can't constraint camera position with Tracked Pose Driver

Unity Engine

Hi everyone !

I have a problem with my VR camera when I use the tracked pose driver with Update and Before Render. I can’t constrain the position of the camera if I want to prevent it from going through walls. I have to use a subterfuge with the camera offset but it annoys me :slight_smile: If I just choose Update in the tracked pose driver, it works but everything is jerky.
Does anyone have a solution? Thanks! :slight_smile:

Hi,

Don’t believe you should try to change the position of the camera transform at all. It’s for the XR subsystem to move and rotate the camera. Put it as a child to another transform, and move that instead. Make sure both the camera and the parent has the local scale set to 1,1,1. Then I think it should be fine to for example subtract the camera vector towards the wall in each frame, from the parent, to prevent further 6-DOF movements of the player to go through the wall.

Perhaps there are other techniques for it too?

Thanks :slight_smile: That’s what i do. It works but i just don’t know why you can constraint the camera position in Update but not in Update and Before Renderer.
