You found a bug in chimera's POV-ray output. I created a ticket for you,
so you'll be notified when it is fixed.
Currently, the only workaround is to set the POV-ray options to keep the
input files and save an image with POV-ray, so when it fails, you have the
image.ini and image.pov files. Then you'll need to edit the image.pov
file and change the refererences to the unknown texture to a known one
(see the #declare's at the top of the image.pov file). And, finally, run
POV-ray by hand:
CHIMERA/bin/povray +Iimage.pov +Oimage.png image.ini
FYI, with this simple workaround, the mesh is all one color.
