[Chimera-users] Visualisation in Headless Chimera

[James Starlight]

Thank you very much, Elaine!
The only thing is to understand why "set silhouette" produces crush at
the stage of the image rendering both with chimera-headless or pow-ray
rendering ;o

Still this is only a small subset of the things one could possibly change in povray, so if you’re a POVray expert you could fiddle with the POVray conf file (see Chimera Log for where this would be), and possibly re-run povray directly using the Chimera-generated .ini and .pov files (from the “copy” command with “raytrace”).
