hi
i can't seem to be able to use creases on edges for poly models at the SOP level and have this go up and effect the final model when rendered with the option - “render as subdivsion surfaces”.
i see that the creaseSOP works with the subdivideSOP,(wich i don't want to use)….. but i've tried the primitiveSOP and the pointSOP with the weight attribute to no avail.
how can this be done?

Oh wait - a bell is ringing. Isn't this all tied up with the bull#$%t legal business of Pixar where they're claiming a patent on crease implementation in rendering subdivs? It's OK for SESI to recreate it in the modeller, but I think they're not risking including it in the renderer.
So if I'm right, you can thank the lawyers. God, I hate the direction this business is taking. :evil:
Cheers,

Betty,
I have never used the render as subdivision surface. Call me old fashioned but I use the SubdivideSOP instead.
I've found it safer, better to texture, and a facetSOP aftewards will correct the averaged normals. Just set up a switchSOP and make your light geo. the displayed geo and just set your render flag where you need it.

Whydoes it seem that so many software developers hold on to their technology for dear life? Does Pixar not license technology? What about A|W? They both have some interesting patents, and often it's not critical to the success of their software that they keep them from the rest of the industry. Why don't some of these companies enter into technology licensing or sharing agreements? I'd think it'd be good for the companies and good for the end users.

Well, of course, for money.

I know Pixar is fiercely holding on to it's motion blurring algorithm - and the fact is that mblur in Pixar's renderman looks better than anyone elses. As far as this particular issue, I agree that it seems quite petty. Note that SESI probably *could* implement it if they wanted to - they're probably just playing it safe and avoiding the risk of a “cease and desist” letter. That's the big danger to the industry - everyone starts walking on glass over what they can and can't implement.
*sigh*

Exluna being the sadest example…
I'm always reminded of the Onion story about Microsoft patenting 1's and 0's…. :?
