Screen-space human skin implemented on V-Ray for 3ds Max that reduce render time 90%

any news on removing the green effect from sss2? Its popped up on a current project I'm involved with.

Thanks,

Well, the only solution so far is to make the scatter color more red.

Hi Vlado,

I get the opposite result .. the more I get the scatter color more saturated red, the more the greenish effect I'm getting. In fact, it's the opposite we have to do, making the scatter color closer to the diffuse color, just a bit more reddish then the diffuse... that's a conter bug worflow for now, not perfect but not so bad. also, having a map for controling the radius help too.

any news about this new SSS2 code Vlado? Can I try it out and let you know my feedback?

HI Vlado,

How things are moving for the skin shader?

Here's a great article about the Quantized diffusion instead of the dipole one : http://www.fxguide.com/featured/prom...wed-vfx-space/
great article and comparaison, let me know your though

[vlado]

Still working on it bit by bit, but I keep getting sidetracked into other things...

Best regards,
Vlado

Can't wait to try it out and give you my feedback

Hope we have something soon to play with

Hi vlado, can we have in the next update the opacity slut in the sss2 ? It will simplify a lot my workflow.. and save render time I guess too.

I crash my motorbike today and this comment just made it all 'OK'

Yep The Quantized diffusion paper is cool, the results are really impressive. I especially like that you don't loose all the surface detail. We use SSS all the time at the office and its a constant battle to try and retain the specular and diffuse information.

my understanding is that this particular technology is patented and cannot be reused.

haha yeah, I mean SLOT lol

I dont think it's patented, I think it's public.
and yes, this technology is better for retaining the details of the bump map, having no green effect, no rebounce of light near close edge at angle, etc. In fact, for now, it's the best skin shader paper. Vlado you should really try to copy it and call it Vray skin shader and be the first renderer to implement it

we looked at its patents when we were developing our sss model for a project and I do not believe it is publicly available.

Did you took a look a this pdf : http://delivery.acm.org/10.1145/1970...10ff609ac68ac4

Looks to me there is enought information there to rebuild it, no? I'm not an expert in the field so tell me. I tought that with all the math explain, one can rebuild it in an other package.

As Dmitry hinted this seems to have a patent so it is not only a matter of "beeing able to implement it"

I hope it do not have a patent on it.. it's goona slow down the progress...
