Hello,

I'm trying to render a picture with POV-Ray using a pov file generated by
VMD. Unfortunately, POV-Ray crashes at the following line:

// MoleculeID: 0 ReprID: 4 Beginning polyhedra
VMD_triangle(<-0.28497034,0.30557495,2.2290211>,<-0.28497034,0.30557495,2.229021
1>,<-0.28497034,0.30557495,2.2290211>,<nan
Parse Error: Expected 'numeric expression', undeclared identifier 'nan' found
 instead

The problem comes from the polyhedra representation used on some part of
my system. From what I understand about the VMD_triangle macro, it looks
like a corner of the polyhedra is missing in the pov file. Does someone
have ever faced this problem?

Cheers,
Nicolas
