I really would like to know who has done this render...
and if anybody has any idea of how it has been done...
really, i love this shot and i would like to reproduce something of the same kind...

That was a experimental Sub-Surface Scattering test done by Matt Fairclough back in 2004 using an earlier version of Terragen 2 Alpha. Sense Terragen lacks SSS i can't see something like this being reproducible. I have to wonder it he used multiple scattering SSS?

I wonder when we can see "sss" in Terragen 2 :P

I did something sort of similar last February:

I think what Matt did with the rocks should be easily duplicated.  Take a sphere, distort it, then add a default shader as its surface shader.  Feed a powerfractal into the colour function, translucency and luminosity nodes, and set your colours to be two shades of blue.  Increase the translucency to 20 or so and your luminosity to say 0.1.  Adjust reflectivity accordingly.  Here is a 5 minute test with file.

Who knows. After over three years it would be nice to see real SSS. The beauty of SSS is you get all that colored light scattering that is bouncing off of the inside ghaving both well lit sections and darker sections according to the objects density.

I'm afraid it's the difference between rendering something as an R&D project and actually turning it into something that people can use without complaining about massive render times ;) Unfortunately there have been too many other priorities and I was never able to turn this into a shader that I would let people use.

Just because milk is white doesn't mean that clouds are made of milk.

Confusoid

Oh darn and i was hoping for all of this.    ;D


Seth

thanks Ryan, I was doing the same thing you did ! (exactly the same way)
thanks for the quick answer Matt.

RArcher

Hmmm, seems I am fighting against the system  ;D  Hopefully this makes an appearance sometime in the future.  But for now, here is another test trying out a different method to try and simulate the same idea.

What about using a water shader with low reflectivity and a powerfracal in the volume 1 input for internal scattering simulation?
Howgh!

But it will be available at some point, right?

i tried the water shader but didn't manage to do something good with it...

Not trying to be a smart ass, but perhaps you should remove that sample image from the planetside gallery because it is misleading to prospective buyers who are not aware that TG isn't able to render (SSS) at this time.

mmmh buzzzzz is right...
I don't think it's a good idea to have a picture that we can't reproduce in the TG2 Gallery :s

RArcher

I'll have another update shortly, but I think it is very possible to obtain a similar result to the original image.
