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"

Fade to color. Performance

In a material, if I make it so that the Normal or Diffuse texture fades to a certain value, will I see any performance improvement?

The moss material in Starter Content has a normal map that fades to blue when the pixel is far enough. That is what I'm talking about.

Thanks in advance :)

Nope, there is no benefit from that. Performance will be the same. Starter content fade to flat normal was most likely done to reduce noise in the scene.
