Hi Greg, transforms.inc comes standard with the POV-Ray distribution, so if it is missing, then something is wrong with your POV-Ray setup. The Axis_Rotate_Trans macro from transforms.inc makes a rotation matrix for an object, so if it is removed, then the various objects are placed incorrectly. Are you using chimera's version of POV-Ray? And if so, which version of chimera on which platform (Windows, Linux, etc.)? If this is chimera's bug, we'd like to fix it. - Greg On Fri, 22 Feb 2008, Greg Williams wrote:

I would like to render my files externally in POV-Ray, but I get error messages. As a test, I set the leucine zipper in wire mode and exported the file. I opened POV-Ray, turned on antialiasing and rendered at 640x480.

I immediately get the following:

Possible Parse Error: Could not find file 'transforms.inc' File zipper.pov line 6

Parse Warning: Check that the file is in a directory specifed with a +L switch or 'Library_Path=' .INI item. Standard include files are in the include directory or folder. Please read your documentation carefully. File zipper.pov line 6

I cut the line �#include �transforms.inc� and rendered again, and I get a new set of parsing errors, which include a couple errant bracket symbols that I managed to fix, at which point I get:

Parse Error: Expected 'object or directive', undeclared identifier 'Axis_Rotate_Trans' found instead File zipper.pov line 1322

So I cut the ending lines of the file:

Axis_Rotate_Trans(<0.000000, 0.000000, 1.000000>, 0.000000) translate <0.000000, 0.000000, 0.000000> } }

Now the render works. I guess I should be happy with that, but I�m wondering what it was I cut from the file. Any help here?

Thanks,

Greg
