There is a bug in raytracing when clipping and capping surfaces. It also occurs when clipping multiple surfaces without capping (e.g. two contour levels of a volume). I've entered it in the Chimera bug database, but 5309. http://www.cgl.ucsf.edu/cgi-bin/gnatsweb.pl?cmd=view&pr=5309&database=chimer... There's no way to work around it short of hand-editing the povray input file Chimera produces. A viable alternative to raytracing is to use silhouette edges (Tools / Viewing Controls / Effects) to put black edges around surfaces with a light color background. I use edge width 2 or 3 and supersampled image saving (3x3) and generally prefer the appearance to (working) raytracing. Tom
