Is there any way to bump up the limit on nested refracting options? I
have 256 MB of physical RAM in an NT system, yet I get this message
often
(too many nested refracting objects.) In fact, by simply moving the
camera closer into a scene, a perfectly renderable file is no longer
renderable.
Best,
D.

  I have never seen this message before. How exactly do you get it?

By having a ray that is inside 100 or more objects at a time.  This would
be easy to achieve with lots of triangles, bicubic_patches, or other
patch objects that the ray never leaves.  To change the limit, you can 
change MAX_CONTAINING_OBJECTS in frame.h to a larger number and recompile,
but be aware that each containing object takes up a bit of memory.  A
better fix would be to not add independent (i.e. non-union) patch objects
to the container list, but that might get ugly.
