Odds and ends

Here are some questions I got from Bart. I'll go over them on Thursday night.

1) How can Subdivision Surfaces be added to the polygon building workflow? I understand that one can just convert the model to SubD,s and continue working, making creases and getting all the SubD details, and then convert it back to Poly’s. But won’t all those details be compromised or lost when converted back?

2) Please demonstrate how to create a Z-depth pass.

3) Not to take up class time with this, but last week you demonstrated how to create a fully reflective ray-traced object ( two toruses actually ). I recall that moved some material sliders to zero and that you assigned a file you created called “toyroom_refl.tif” into the Reflective Color node. In any case I’ve been unable to recreate the image you came up with, which was: a totally reflective surface with an environmental map as well. ( I may be confused on one or two parts of this recall of events )
