Educated guess: Try changing your regional OS settings to use
the period as decimal separator. If PoseRay uses a conversion
function which is locale sensitive, that would cause it.

Thomas,

PoseRay can handle lines two ways:

1) Export them automatically, if they are visible, as sphere sweeps. 
They would be constant width.

2) Convert them in the geometry tab to tubes. Once converted the tubes 
become part of the mesh and will be UV mapped. You may want to turn the 
lines off in the preview tab before exporting so that the sweeps are not 
exported.

This may not be too clear on the manual and I will look into that.

I will investigate the problem with the overwrite and the comma 
delimiter. I have been careful to force comma for separator and period 
for fractions no matter the windows locale.

Thanks for the bug report. Let me know if you find anything else.

Ah, I have to look into this. I certainly overlooked something there. I 
converted to tubes and got the sphere_sweeps too as I did not switch the 
lines off before exporting. Shall try again.

The suggestion for the Windows locale is worth investigating. I shall look 
into it and see if it makes a difference.

OK. If anything turns up, I shall report back.

1) So, I can confirm that the educated guess by Christian Froeschlin is 
indeed right. The locale/regional OS settings influence the way in which the 
delimiters are written by Poseray export.

2) I would suggest a small addition to the manual.
Under the heading: Converting Lines to tubes (Lines sub-tab), I would add a 
reference pointing to the POV-Ray Output Tab, line thickness section.

3) Remains, for the time being, the overwrite bug.

For a further discussion about the use of the hair tubes, I would like to 
point you to the povray.tools.poser n.g.

Ok. Just forgot a point 4.

4) Exporting the tubes to POV-Ray, excluding the lines/sphere_sweeps, 
results in an empty union block:

//lines as cylinders
#declare poseraylinegroup=union{
material{Hair_}
}

Which is then added as an object{} in the model assembly at the end of the 
file.

While this only generates a parse warning, it is a bit crooked in terms of 
code.... ;-)
