Hey Horward, glad you responded to Michael, i missed it somehow and thank you for checking other vids too :)
Escher glossy shader is a bit more than just a lookup, it samples additional points from the lightprobe based on simple importance sampling and then it further allows you to prefilter each sample, the prefiltering is done via an on-the-fly precomputed integral image . Such combination allows a speedy and two-level control of the glossiness. By the way, the SH can do phong shading if you prefer another look. SH + glossy are good friends :) Best, Mike On Tuesday, June 4, 2013, Howard Jones wrote: > Think you're supposed to buy it not take their trade secrets ;) > H > ------------------------------ > *From:* Michael Garrett <[email protected] <javascript:_e({}, > 'cvml', '[email protected]');>> > *To:* Nuke user discussion > <[email protected]<javascript:_e({}, 'cvml', > '[email protected]');>> > > *Sent:* Monday, 3 June 2013, 17:40 > *Subject:* Re: [Nuke-users] [plug] Escher Spherical Harmonics tools > > Thanks for posting this!
