> Cool -- thank you for keeping the pie rolling! Chances are pretty high I found some of your code laying around on the interwebs and used that to figure out how it all works so you probably deserve most of the credit;) Matt Ebb did a C prototype way back when and gave me his code but it was too complicated to help out with the python one I ended up writing. Honestly I haven't been keeping up with what blender is doing since I can't even open the new version due to my videocard being too old. I'd be nice to get back to blender hacking (have some ideas on compiling down the node trees using partial evaluation) but can't see a new computer happening anytime in the near future.
