[chimerax-users] VR mode not working

[Sebastian Poelsterl]

Hi Tom,

thanks for your help, the latest nightly build works perfectly.

Is it possible to modify the key bindings of the Oculus controller, e.g. to enable/disable rendering the protein's surface?

Best regards,
Sebastian

Hi Sebastian,

  This is fixed in current ChimeraX nightly builds.

  This ChimeraX VR error was caused by an automatic SteamVR update a week or two ago.  Unfortunately SteamVR now generates a harmless OpenGL "invalid operation" error when ChimeraX hands it two eye images.  It does not clear the error state and then ChimeraX sees the OpenGL error and gives the traceback you saw.  I have worked around this SteamVR problem by clearing the OpenGL error after handing the images to SteamVR -- the error actually only happens when ChimeraX gives SteamVR the images the first time.  SteamVR code is proprietary so I have no easy way to debug what is giving the error in the SteamVR runtime.

        Tom
