[Chimera-users] Enhancement request Povray

Hi Richard,

  In our development version of Chimera (1.4) there is an option in the 
Lighting panel (menu Tools / Viewing Controls / Lighting) called 
"quality" with settings "normal" or "glossy".  The glossy setting gives 
a shininess similar to raytracing by doing per-pixel light 
calculations.  It also gives higher quality transparency.  It can be 
used with normal (unraytraced) image saving to produce shadowless higher 
quality images.  You would need a Chimera daily build.


This can be installed without uninstalling your production Chimera version.

  Greg Couch develops our raytracing code and would be the one to 
comment on the "no shadow" option.

I experimented with modifying the povray output and added the "no_shadow" keyword to all objects included in the file. This did the job. Could you please add a "no_shadow" option to the povray options panel? It would be very helpful.
