I've attached a couple of zip files, with two images in each. They show
the differences between rendering in POV-Ray and rendering in BMRT. The
UV's seem a bit messed up in the exported RIBs, though...also, the
parameters to the plastic shading style in BMRT are far different from
the parameters to the POV-Ray standard finish for textures.

its quite nice to see there is very little differemce in these two renders,
kinda shows the quality of povray.

on a side note, i tried a few test renders, but kept getting the message
that the povpointlight shader could not be found, even tho it was in my
shaders dir, or anywhere i put it.

AFAIK, you need to set path = youshaderdirectoryhere or add this line of code
to the RIB file:
Option "searchpath" "shader" ["youshaderdirectoryhere"]
the setting the path thing is the best idea, IMO.

Well, depends on what you mean by quality. POV-Ray doesn't have programmable
shaders...I'd rather dare you to compare the quality of the two when that is
taken into consideration. The shadows are a bit weird, as they don't seem to be
in the renderman standard(and the usual arealight trick doesn't seem to work
too well in renderman). But then, neither could you do something like
windowhighlight.sl- try cutting that from this
site(http://www.renderman.org/RMR/Shaders/RCShaders/index.html), compiling it,
then applying it to an object. Its pretty impressive. Or use windowlight
instead of a standard povray light(just change the name in the RIB file).

Or if you really want to see what can be done with BMRT, look to this page:
http://www.bmrt.org/bmrtgallery.html
Specifically, I'd suggest looking at this image. Its really awsome:
http://www.bmrt.org/bmrtimages/merritt-fruit3.jpg
Nothing in it is an image map- everythings procedural and antialiased.

In that case, I'd suggest that you just add that line to the RIB file before
rendering. I haven't been able to get the autoexec.bat thing to work
either-xander just told me about it. Perhaps you ought to ask him.
