Dear Elaine, Eric, Tom, and team, I am happy to see ChimeraX is continuing to move forward! Here is a little request. For the figures that I am now making for publications, I have a special interest in showing semitransparent molecular maps together with the corresponding models, with ambient occlusion lighting on. I think ambient occlusion makes this kind of figure much easier to interpret and more beautiful. What I have noticed is ambient occlusion seems to get automatically turned off as soon as a map becomes less than 100% opaque. I always assumed this was due to some kind of rendering difficulty. But then, I noticed that sometimes I can “trick” an old version of ChimeraX to do exactly what I want! Below is an example. Basically, in ChimeraX 0.6 I can set up everything just the way I want with an opaque map, then turn down the map opacity and get a nice, pretty figure just the way I like it. But then, as soon as I show/hide anything in the Model Panel, the ambient feature gets turned off! I noticed that in the most recent daily build, this “trick” no longer works and I can’t seem to ever get the pretty combination of transparent maps and ambient occlusion lighting that I like. I sure would like to have this option! I guess there must be some reason it is disabled? Best, Chuck Sindelar Opaque map + PDB (ChimX v0.6) (pretty but the PDB is obscured) [cid:image001.png@01D55FF9.D8266CF0] After adjust to 80% map opacity (ChimX v0.6) (pretty!)
