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"

[Material function] What does a material function "Distance_Blend"?

As description says: "Sets a distance and range to blend from 0 to 1", but it doesn't really help me a lot. Or maybe I just don't getting the idea.

What that function actually do? Where I must to use it?

So I found zero documentation on this and decided to just experiment and figure it out for myself.

It looks like the distance_blend node just makes a gradient from 0 to 1 across a distance that you specify.

I believe this would be useful in a case where you want to blend micro and macro textures together.
