Blender Tutorial: True Cycles SSS


https://i.ytimg.com/vi/e4390it63MU/hqdefault.jpg



Cycles has an awesome new feature: a true SSS shader! Download the latest development build from: http://builder.blender.org/download (warning: builds are not stable). As of now, SSS doesn’t support CUDA(thank you Stephen Bates in the comments below!).

  1. Thanks for the great tutorial! The greenish color comes from the diffuse bounces. I tried to make a flattened sphere and it worked perfect … I only saw the SSS color (set in radius) showing through the edges.

  2. Neat demo, and it (more or less) works that way currently in 2.69.

    I think I figured a way to make SSS somewhat more predictable as far as RGB radius settings are concerned. With the right nodes it's simplified to just using a color input and strength multiplier.

    Also the SSS shader seems to be one that shouldn't be used by itself. (You can, but it looks…meh.) For good results it always has to be mixed with another shader type.

    It's easy enough, so I'll likely post a short video on it fairly soon.

  3. i think it's because RGB rays scatter in 1:1:1 number ratio, but when you increase the red radius it has more volume to cover up. so they are more scattered in the beggining which causes the other colors to show up more clearly (thats why it goes away after some time, when enough red rays are calculated to cover the volume densely enough)

  4. Just to let you know, I think the reason you had green/blue coming through is that you increased the red scattering, so more red light will scatter one way, and the remaining green/blue the other.

  5. Thanks! I'm running blender on a 5 or 6 year old mac mini. Two-cores, 2gb ram, and it doesn't support CUDA.

    If your graphics card supports CUDA, you'll have speed of about 30 to 40x my speed. I'm just using an older computer.

  6. Nice video, maybe I missed it somewhere in the video, but what are your specs? I would love to use this for my future models, but not if it's going to be eating up my resources, and killing my CPU. From the video, it seems like the render rate for even the simple Suzanne model is quite low with SSS.
