Thanks everyone for the comments. Curriculum design here at the college and most other colleges in Ontario is guided by a set of ministry guidelines set out by the government...which we just got for Animation this year and the advice of our industry committees. Our industry committe which is comprised mostly of former students, 2D animators, former teachers, etc... have said that nurbs are never used anymore so we shouldn't teach them. Personally, I agree with all your comments. I think nurbs are essential even though we may not be modelling characters with them anymore. Unfortunately, every kid with a cracked version of zbrush is screaming nurbs are dead on the forums and this seems to hold more sway. Thank you for your replies. I need top industry professionals like you to make a case.

I figured I was just being too Houdini-centric and missing some obvious point. It's funny how it's almost come full circle. Way back when, wasn't one of the limitations of Prisms' "procedural" approach that you could only work in ploys ?.. when competing packages offered nurds? Dating myself ? but I think nurds were only introduced in that interim stand alone modeling package. "Sage" I think? Anyway, I'm in agreement with the crowd. Even if there are other methods that may be preferred ? or better for certain task, why does that mean you'd throw out existing tools?

Stop teatching nurbs and subds, ok, and they are replaced by what ?

New subject: simple soap bubble shader
Hey guys. I've finished my first Houdini job thanks to all your help, and I'm keen to do the next one. It is a shot inside a fizzy drink, where I have to make bubbles do things... yes.. my life has lead up to this point!! I've created the whole thing in softimage, and alembiced it into houdini last night, just to see if I can match the look. The first thing I tried was to apply the glass material pre-set to my bubbles, with a environment light and a HDRI. This looks kinda cool, but the render time is through the roof. I then created a new material with the surface model vop pre-set in there, but as soon as I make it refract, the render time goes up again. Where can I start digging for info on setting up a simple reflect, refract shader? I figured out how to create a ramp based on facing ratios, but I cant find things like "index of refraction" At the moment the scene renders fast as hell in mental ray back in softimage, but I would like to force myself into houdini a bit more. Thanks for reading G
