P3DV4.3 VR problems but not in V4.2

Postby SplitFlap » Wed Jun 27, 2018 2:35 am


I have a fresh install of 4.3 however when I select VR (steam VR) I appear to be sitting with a helmet on my head.

This black frame moves around with my head just like a helmet. Changing to mono mode in VR settings removes the frame. However both stereo and single-pass modes show this helmet issue.

I am using the pimax 4k headgear with steamVR. I did not have this issue in V4.2.

In Stereo and Single-Pass Stereo, we are using the stencil mesh to help performance.

The stencil mesh is queried from the OpenVR driver for the headset.

It appears that PiMax is returning a bad stencil mesh. You should report this issue to PiMax.
