Wilian commented that it was a "dumb error": he hadn't turned on a controller

[Tom Goddard]

Hi Wilian,

Last Friday you got an error that because the headset was not found when you used "vr on". Eric reports you said it was because the "controller" was not on. That doesn't make sense. Do you mean the link box (the box that the 3 Vive connectors plug in to) was off?

I think I may make a better error message (instead of the code traceback) that suggests what to look for. But I need to know exactly what the problem was.

Hi Tom,


Yes, you are right, the link box was off! I had forgotten to turn it on but as soon as I did it, then it worked.


Thank you!


Wilian

Hi Wilian,

I see you were using ChimeraX 0.7 from August for this 3-person VR session. That is a very bad idea to use that very old ChimeraX. It probably explains why you were not able to sync volume data. The error message when the headset is not detected is also much better in more recent ChimeraX versions. And of course dozens of VR problems have been fixed. So be careful to not use old ChimeraX for VR.

Tom
