Just so everyone on the list knows. Extrapolating from what Charles said, the error was probably that MegaPOV wasn't able to include the transforms.inc file because MegaPOV wasn't configured properly to include the POV-Ray library files. And on Mac OS X, Linux, and other UNIX systems, to use the CHIMERA/bin/povray.exe program outside of chimera, you need to setup the shared library path to include CHIMERA/lib. Chimera does that setup automatically for many of the programs in CHIMERA/bin, so we should probably fix it for povray as well, but if you're going to use your own POV-Ray anyway, like the multi-threaded 3.7 beta release, then that is not an issue. - Greg ---------- Forwarded message ---------- I figured it out. In MegaPOV you need to set the library path for the render, also POVray 3.6 will not work as a standalone application in Mac OS 10.4 and higher. Charles On May 5, 2008, at 2:15 PM, Greg Couch wrote:

I want to make a transparent surface in volume viewer that can be drawn in POVray. It appears the *.pov and *.ini files produced by Chimera cannot be read by other POVray renders. Is there some work around that will allow me to ray trace a transparent surface displayed by the volume viewer?

That is news to us. The chimera povray output was only tested with the POV-Ray 3.6.1 renderer that comes with chimera. Please submit a bug report using chimera's Help / Report a Bug dialog and include the name and version number of the other POV-ray renderers, as well as the error message you get.

Thank you,
