[Bf-cycles] Hair importance sampling

[Marco G]

Hi all,
here is a link to a new paper recently appeared, from d'Eon - Marschner - Hanika (Weta Digital and Cornell University), coming to next Siggraph Asia, Importance Sampling for Physically-Based Hair Fiber Models.
Current Cycles hair bsdf gives nice looking results, getting rid of noise though is pretty difficult, i'm wondering if this could help perhaps.
Regards, MG
