Hi, I am observing inconsistent behavior in the ‘surface dust’ command. When I launch ChimeraX and execute the following commands one-by-one at the command line everything works as expected. However, if I place the commands in a cxc script, then double click the script ChimeraX launches and the script executes, but the ‘surface dust’ command does not hide the dust. In addition, within that same session I can then enter the ‘surface dust’ command manually and it works as expected. I’m running ChimeraX Daily 0.93 (2020-04-04) on Mac OS 10.15.1. Do you know why the command is not working inside a script? close all open map.mrc turn x 90 volume erase #1 center 175,160,314 radius 100 outside true surface dust #2 size 40 Thanks for the help.
