Hi Drew, You are not doing anything wrong - it is a current shortcoming that not all aspects of the display in Chimera are passed along to Povray. Personally, I always prefer to use the rendering from Chimera (not raytraced) for making clear and attractive images for publication. Here is a previous post on this topic: <http://www.cgl.ucsf.edu/pipermail/chimera-users/2009-June/004030.html> The "image tips" may also be useful: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/print.html#tips> Elaine ----- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco Below is a comparison of with and without raytracing, where the rendering from Chimera includes silhouette edges and ribbon-inside color. I used "publication preset 1" then changed the ligand from sticks to the sphere representation, then saved images with and without raytracing (otherwise default settings).
