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"

Inverting Fresnel

Hi All,

I'm looking to use a fresnel node to create some realistic reflection falloffs in some of my materials. The problem is the node seems to create the inverse of what I actually want. I want the reflection on the edges of the material rather than in the middle and fading to matt on the outside. Basically the exact opposite of this example.

Just put a OneMinus node after fresnel. Or plug fresnel into alpha of a Lerp and switch the A and B parameters.
