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"

How to test scene depth against custom depth in a post process material

I'm working on a game which involves a big "kill-sphere" and I want to do a custom-depth effect so that everything outside of the sphere is orange. I have partly achieved this but since custom depth doesn't test against scene depth, the sphere appears to be visible through the floor. Hopefully the pictures better demonstrates this.

stop lookin at the text!!! look at the picture dummy

Having only one custom depth, you can only test if scene is behind the sphere, or in front of it, but not both at the same time. Consider using sphere mask material expression and supply sphere position and radius externally.
