Explanation of Sub Surface Scattering?

[CCS]

Well, from a MAX/VRay point of view, that would depend how it's modeled, no?

No Problem DaForce.

Just a quick explanation - the translucency color as I said is the color just underneath the object's surface, the Refraction color is the color just above this surface, and the Fog Color is the color inside the object that fills it. There will be also Examples in the Help about translucency.

Wait a minute... What's the difference between the color just below the surface and the color inside the object? Where does one start and the other end or is it a combination of both?

thanks for all your help guys!

hmmm, how many surfaces does an onion have?

I like parfait, everybody likes parfait. It has layers...err surfaces. Wait...what were we talking about again??

I think this noble steed will wait untill the translucency tutorial arrives...

Take a look at this:



What we have here is a green diffuse and orange fog colors. Refraction is half gray. The refraction color plays the role of a shutter between the diffuse and the fog/translucency. The whiter it is, the less diffuse you have. Here is the same with white Refraction:


No green diffuse.

@ ngrava: there is not a clear line between the fog and translucent colors, because they are multplied for the final result. I put the map in the Translucent swatch in Daforce's scene just to show him that there is a way to see it on the flipped side of the object using Translucency.

@ flipside: Maybe it is better to say that refraction is just above a given point just underneath the object's surface. Translucency is just below that point, and Fog is deeper down. Diffuse is above Refraction. That's why Refraction plays the role of a shutter, that's why you can see through an object when it has refraction on it (no translucency). This concept doesn't work on layers, but it is better explained like this, that's why I said surface. Look at this:

Much clearer... Thanks alot.

Cant wait for the tut.
