Re: [GSoC 2013] Advanced Rendering Techniques - Skin/Hair

Hi Alex,

I am familiar with your code and blog, is it possible to understand what
when wrong? Maybe I can try to improve the implementation and add the dual
scattering model as part of the GSoC project this year. Also, the skin
shader implementations does not seem to be based on actual subsurface
scattering but actually on approximations. So, i think it might be better
to have a physically realistic model than just a hack. Thanks for the
reply.

Regards,
Giris
