I am testing the conversion of Dynamic Hair from Poser towards POV-Ray. Just 
using the default settings for converting lines into tubes, I get the 
following parse error in POV-Ray:

File: Name_POV_geom.inc Line: 60
File Context (5 lines):
<vector>,0,1
<vector>,
Parse Error: Float expected but vector or color expression found.


This refers to the first sphere_sweep in the file, which looks like this:

#declare poseraylinegroup=union{
sphere_sweep{cubic_spline

}

My hunch is that it is the tolerance parameter which is at fault here?
