I don't think you're wrong.  My reply is why not have both?  The
hardcoding can save on render times if all you want are simple variancew
along the Z axis or a radial change, but being able to include one's own
designs is very very nice indeed.

As to the compiling process used by BMRT- there is NO reason this needs
to be, the renderer should be able to parse it's own darn procedurals-
perhaps a memory sacrifice in order to pre-compile before execution
would work if on-the-fly would be too slow.  At any rate one could write
a simple util to automate all this anyway- I'll take all the power I can
get in my textures! :o)
