Subject: Carrara and SSS


mysticeagle ( ) posted Fri, 23 November 2012 at 5:51 AM · edited Tue, 05 November 2024 at 6:43 PM

I see that the default carrara shaders folder has its own SSS shader section. Can anyone tell me whether the Poser SSS shaders that appear in mat poses folders will work in carrara?. I've tried a few of posers basic mat skins and i'm not really impressed with the quality of the output.

No they dont work in Carrara. Carrara use just one color to create the depth, so maps dont worlk in the SSS channel yet.

Anyone tried to mix SSS channel with Glow or Transparency or something other that may come closer to real SSS map support?

Here's an attempt I made a while back using the Multi Channel Mixer to get a more desirable SSS effect.

Basically I used a standard V4 shader tree in the first channel, and the same tree in the second, only with SSS and translucency turned on. For the blender, I made a gray-scale map to dictate where the second channel showed through. (Ears, nose, cheeks, etc.)

I don't think I even spent 20 minutes working on the setup, so I'd imagine things could be fine-tuned for much better results. Still, I like this a lot more than the wax-figure stuff I see coming out of Poser 9 :)

Nice, got any details to share? Screendumps, numbers, anything?

I set this up quite a while ago, but I'm pretty sure the tree in the included screenshot was what I used for the final render.
  • Source 1 is a standard V4 setup with no SSS or Translucency
  • Source 2 is a copy of the first tree with SSS and Translucency turned on
  • For the blender map, I started with a standard V4 diffuse map and painted pure white layers over any areas I wanted thee SSS effect to show through. When I was done with the white, I just filled the image background pure black. (This is an area that could be improved by a more talented artist!)
  • For the SSS channel in the second source, I went with a dark red color and turned the diffuse reflection up pretty high.
  • In the Translucency channel, I used Ringo's Reby Sky shaders from DAZ.
  • Rendering time was much, much faster than with uniform SSS
  • I was also able to light the character any way I wanted to without running into the problems that SSS and Translucency usually cause. (Blotches, artifacts, etc.)

Again, I'm sure there's better ways to do this, but it works for me!
