Hi,
I'm currently playing around with Renderman (various implementations)
and I've got a texturing problem I can't seem to figure out.
Look at this image:
http://www.cs.unc.edu/~sewall/texproblem.jpg
That is a polygon mesh with a texture UV mapped to it; the mesh was
generated & textured in Blender (looks great there), then ex****ted
with a Python script (one I wrote) into a .rib file.
Clearly, there's something wrong here. At first I though the problem
was the precision of the (s, t) coordinates, but after re-loading the
ex****ted mesh into blender, it looks fine.
I'm pretty new to Renderman and I can't figure out what's going on.
Any ideas?
Jason
P.S.
The relevant part of the surface shader is:
tex_color = texture("skyscraper.tx", s, 1.0-t);
P.P.S. I've tried this in Pixie, Aqsis, and PRman with similar results
each time.
