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?

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

Hi,
I'm trying to view a PDB structure (2fha) in vr mode, but get the following error after executing 'vr on':
An error occurred in drawing the scene. Redrawing graphics is now stopped to avoid a continuous stream of error messages. To restart graphics use the command "graphics restart" after changing the settings that caused the error.

I'm using ChimeraX 0.5 with an Oculus Rift (1.24.0.545657), NVIDIA GeForce GTX 1060 (driver version 391.01) and SteamVR Version 2018-02-10 (1518226924) under Windows 10 (10.0.0.14393).
Any suggestions would be appreciated.
Thank you.
Sebastian
