Hi John,
That render your using is mine and I'm 'billthefish' (at least outside of the UK
Football scene). It was produced using a number of different tools:
L3P
Mesh-Enhancer - http://members.aol.com/elferwette/LDraw/
The FastRad POV includes - http://www.brickshelf.com/cgi-bin/gallery.cgi?f=94173
The LUGNET color definitions include - http://www.pobursky.com/article/4
Basically the steps are:
- Generate a POV file with L3P (make sure LGEO option is selected)
- Run the POV file through Mesh-Enhancer. I had to experiment to find a good
crea angle that smoothed the edge that needed smoothing but left sharp edges
where they were supposed to be.
- Add in the includes for FasrRad and LUGNET Colors
- Render and wait.
If you have any question please don't hesitate to ask.
