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"

Z-fighting alike artifacts in 4.12 ? GBuffer errors?

After switching to 4.12 I've got z-fighting alike artifacts on many objects. They were ok in 4.11 so I assume it's somehow related to the the GBuffer format changes Can I somehow fix it, or switch to legacy GBuffer? Strangely, bugs disappear if I make material 2-sided.

UPD: It turned out that G-Buffer depth doesn't affect much this bug.

Though it was removed by setting Early Z-pass to NONE.
