I am glad you find PoseRay useful. I never got radiositiy or Megapov's
hrdi lighting to work for me satisfactorily so I have been using light
domes for a while now. Although it is not as accurate a representation
the lighting effect is very similar in many cases.
I do not have any artistic ability and the pictures on my galley are
just test renders that have come up better than I expected. Hopefully
someone with talent can create some nice images using light domes. I
included two light dome files in the PoseRay distribution.

Excellent program. Used it last night to convert a .3ds file exported from
Blender to POV-Ray. I like the way you handle the materials. I did something
similar with a exporter for Animation Master and it makes it so much easier
to touch-up the exported files.

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
20

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

In POV-Ray Output \ Export \ Save
Checking or unchecking the <Overwrite files> option does not work. Files are

Testing this further, I find that there is a conversion bug or a writing to
POV-Ray bug. The output should be:
<0.916469,74.4353,2.32733>,0.1
instead of:
<0.916469,74.4353,2.32733>,0,1
In addition, the sweep thickness values for the root and tip diameters are
not converted correctly, probably as a result of the above. Whatever changes
are given, the result always remains <vector>,0,1

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.... ;-)
