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"

4.11 Hair shader blue dithering on sss profile

I'm currently playing with the 4.11 hair shader. The dithering works for me, until I put a sss profile material on the head. Then, the dithering tints blue somehow.

What I tried:

  • changing sss profile colors -> If I pick a blue color on the sss-profile, I can change the dithering color to a red-ish one, but the skin looks aweful then :/

  • playing with the hair shader tangent colors -> kinda reduces the blue effect, but the anisotrophic reflection gets worse

Here's a screeny, any ideas?

The answer seems to be, that both, the dithering from the hair shader and the scatter-radius feature of the sss-profile skin shader are post processing effects, which get in their way of each other. If I turn down the scatter-radius, the blue dithering artifacts dissappearing but I barely can see the sss effect with scatter-radius turned down, until the blue-ish dithering is almost gone.

Hopefully, someone from epic will see this and know a way around this, cuz I can't reproduce the nice skin effect with the other "subsurface" shader model like intended.
