Hi,

can someone help me writing a simple shader for BMRT? I'm trying to
apply a tutorial from the "3D Photorealism Toolkit" book (Bill
Fleming) to BMRT. It's a simple battery model which should be rendered
with the help of 5 textures:

- color image map
- reflection image map
- diffusion image map
- specularity image map
- bump image map

The original model is a DXF file. I loaded it into Blender and applied
the textures. Which results in
http://www.janw.gothere.uk.com/Images/battery.blend.jpg (I'm not sure
if everything is correctly applied but the bump mapping looks nice). I
can use my export script to write a RIB file (with st-coordinates). I
used the "paintedplastic" shader to produce the image at
http://www.janw.gothere.uk.com/Images/battery.rib.jpg (so the texture
for the color should be no problem even if the st-coordinates are not
100% the same as in Blender's cylindrical mapping). Can someone help
me with writing a shader which takes the 5 textures and applies them
to color, reflection, diffusion, specularity, and bump? Any help would
be appreciated ;-)

Cheers,

Jan
