Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Blending SSS shader with SkinShader in a layered Material

Hi guys,

I'm currently working on a project where we would like to combine the SSS shader and the skinShader in a Layered Material so we could have the skin shader on most parts of the head, and get the SSS only on certain parts (ears, tip of the nose, etc...).

When used individually, the SSS and the skin shader works fine. However after creating two material functions, copying the SSS and skin networks to their respective Attributes, and combining those two Material functions into a third one with an alpha, the SSS doesn't work. We did the test with very simple materials (red and green) and they blend fine.

Am I missing something in order to enable the SSS when creating the material function ?

Attached the standard material network, one of the two material functions and the combined one.

Thanks in advance for your time.
