Hey everyone!
This week, we’re going to be looking at how what we learned last week applies to the Sub-Surface Scattering (SSS) Physical Material in 3dsMax and mental ray. They’re very similar, but the physical material gives you a little more control over the final outcome. Since this is both a shader and a material type, what you learn here is applicable across many applications!

Great one! I’m going to try this out on that model (tree thingy) I sent you to see if I get better results then I had with the fast skin.
My problem with SSS has always been tryng to make the diffuse blend well with the scattering.
I let you know how my renders turn out. THANKS!

I tryed to reproduce this tutorial using my own setup, but I ran into a few problems:
1. I keep on getting the error: PHEN 0.6 error: A ray encountered an invalid color.
2. Can this be used with Final Gather instead of GI?

Eww; that’s a nasty one, Spencer. I’m not sure why it would say that, but I know that sort of thing happens a lot when you’re working with odd materials. Are you using any strange lights (i.e. photometric vs an ordinary spotlight or mr area spotlight)? Are you using any extreme values (i.e. really big or really tiny scale conversion factor, scatter depth, etc)?

I’m using a photometric light… Don’t they work with this material?
I’ll try out different lights…
Thanks for the feedback.
I did manage to get a really cool (and realistic) effect with the Fast Skin material with this other test scene.
It would be cool if your site had a forum so that your readers could post their experiments.

Tryed different light setups (standard and mr area) and I still get the invalid colors error.
I guess SSS Physical material is somehow broken in Max 10.

im having the same problem with Spencer. i tried everything but i cant fix hit. im using max 2010. here the error message;
“PHEN 0.6 error: A ray encountered an invalid color (NaN), using black instead.”
and thank you for the tutorial… 😉

I love this tutorial. Is it possible to download your monday movies? I feel that there are so many that could help me.

The tutorial seems great but I can’t reproduce it at all. ):
No matter what I set the scale conversion to, I never get any rainbow of colors on my mesh, and I made sure GI is on. Did you do something special to the lights maybe that you didn’t say?
