Try "camera sbs" and see if shadows look right. If they do look ok, but stereo does not then it will require some debugging with a stereo system that reproduces the problem and I am not able to test that until quarantine is over.

Thanks. I will check out the versions as they come out. Hopefully this can be fixed. I can try a VR and see what is up with the display if anything.

Subject: Re: [chimerax-users] 3D stereo lighting is not the same as mono

I made a bug report for this

https://www.rbvi.ucsf.edu/trac/ChimeraX/ticket/3315

I am not able to test stereo, don't have a computer that can do it. For me other two eye modes like VR and SBS (side-by-side) have correct shadows. The problem may be a graphics driver bug effecting shadow calculation. Or it might be a bug in ChimeraX in how OpenGL quad-buffering are used.

I am using version 1.0 in Centos7 with Nvidia 3D glasses and K4000 video card. I do all my work in 3D stereo. Especially density fitting. I noticed that the lighting is different in mono vs stereo mode. When i go to stereo mode with

camera stereo

the image is in stereo but the "full" lighting is on and the image is very dark with shadows. If I switch to 'simple' it is bright and has weak shadowing. Switching to 'soft' the image is flat black and can only be seen with white background but contains no atoms. I think this is a bug.

But a Great improvement in rendering of images.

thanks

p.s. old chimera does stereo very well on my system
