I have a question about the SSS Dry Snowball example.
There is something I don't grok about the node setup: the two material mixers at 0%. How is that first texture contributing to the results? Even better, why does it work?
Only the last mixer has a number, 50%.
I sure do appreciate the insight into such a node build.
