My old web pages (see http://www.q-bus.de/Blender/ and http://www.janw.gothere.uk.com/) are dead (not updated) for quite a while. Just in case people do follow the links and wonder why I do NOT answer any emails concerning this web pages. So I had to start a new one

http://www.wahn.demon.co.uk/
Seeing progress in the new Python API I thought it might be a good idea to work on my export scripts (again). This time I will be a bit more careful publishing stuff (that's why you can't find the export scripts there RIGHT NOW).
Just to inform you: I have started a RIB (RenderMan) and MI (mental ray) exporter. Both scripts use Python. You load the scripts press ALT-P and (on Linux) some files (blender.rib or blender.mi) are written to /var/tmp (can be changed for Windows users). Assuming you have a proper installation for one of the RenderMan compatible renderers (I use AIR and some other RenderMan compatible renderers privately and full lizenses of PRMan and mental ray commercially at work) the scripts renders directly into an existing window (like airshow) or pops up with a image viewer after rendering finished.
Concerning the lights (and other things):
I wrote RenderMan light shaders which do mimic the Blender settings. Mental ray shaders will follow ...
I do not know how much time I can spend on this. And before I publish things again I want to know how many people would be interested. I'm very busy with commercial work (see http://www.mill.co.uk/) and I will publish not only Blender stuff (this time). You will find Houdini, Maya, XSI, RenderMan, mental ray, and other stuff (once I tested things properly) on the same web page. I will grant student from the German Filmakademie ( see http://www.animationsinstitut.de where I will start to give lectures from time to time) access to certain material to make tests and learn about "shader writing" in general.
Concerning Blender I will NOT publish my new email addresses on the web page because I just don't have time to answer all this emails. I will check from time to time this forum and I might give selected people early access to the things I have done in case they want to contribute. Dependend on how things work out I might give everybody access to the experimental stuff ...
Cheers,
Jan
