  Thank you for your replies to my questions. In regards to the
term caustics as used above I have one more little question.
With the photon patch is it necessary to use the caustics interior
modifier for the caustic reflections ? It doesn't seem likely to me
but I have not heard explicitly one way or another on the this and
would like a clarification for sake of proceedural accuracy.


  Again thanks and that disco ball is almost finished. :)
