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. http://www.cgl.ucsf.edu/chimera/alpha-downloads.html 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. Tom Marhoefer, R (Richard) wrote:
Dear Development Team,
I would like to generate raytraced images without any shadows. The shininess however should be retained. 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.
Kind regards, Richard
