How to exit VR mode?

[paulmelis]

I haven't found a way to exit VR mode, once you're in it, other than restarting instant-ngp. Is there a better way?

Hi, when you take off your headset, instant-ngp should automatically return to single-view rendering (at which point you can re-enter VR by putting on the headset again).

Does this not happen for you? If so, which headset do you have?

The disconnect button works fine, thanks! The dropdown for the blend mode is a bit weird. It contains (with the XR-3 here) a BlendOpaque entry and a H? entry. The first one works as expected, but I don't know where the second one's name comes from. It also doesn't change the blending as far as I can tell (can still see the checkered sky dome).

Edit: and I don't have a dev environment set up here to set m_print_environment_blend_modes to true to see what gets reported ;-)

Edit 2: Ah, OpenXR Explorer does list the supported blend modes on the XR-3:

Edit 3 (sorry for the mess): the 2nd entry's name is not consistent over different runs (H?, ?, ??), so could be an invalid memory access of some sort. I do see a change in skydome rendering, btw, but only after switching away from blendopaque and back to it again. The skydome then turns black.

Whoops -- I'll fix the dropdown, my bad. In the meantime: does the black sky dome turn transparent if you disable DLSS (after switching back and forth in the dropdown)?

[paulmelis]

No, DLSS yes/no makes no difference in BlendOpaque mode

Thanks for checking. Unfortunately, I don't have any bright ideas about what else could be broken. I'll get back to mixed reality once I have a local test setup. (The dropdown is fixed on latest master in any case.)

Okay, with your latest updates the Blend mode now works!
