[Chimera-users] transparent background

[Elaine Meng]

Hi Dmitriy,
For images directly from Chimera, it depends on your computer.  The  
setting is in the Effects tool (Tools... Viewing Controls...  
Effects).  If not possible on your computer, I think there will be a  
message that says so when you try to turn the option on.

For images raytraced with POV-Ray from Chimera, there is a separate  
setting in the "POV-Ray Options" section of the Chimera Preferences.   
One way to show these options are by choosing File.. Save Image,  
setting the raytrace option to "true" and then clicking the "POV-Ray  
Options" button. Depending on your version of Chimera, it is  
described as an alpha channel or transparent background setting.

Ray%20Options

As noted in that manual page, you also need to turn off depth-cueing  
in Chimera (in the Effects tool mentioned above) to get a transparent  
background in the raytraced result.

I hope this helps,
Elaine
