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"

Is it possible to disable Z-Buffer?


Is there a way to disable Z-Buffer? Profiling shows huge amount of resources in PosOnlyOpaque. I tried r.EarlyZPass 0 but has no effect in ms

Z-Buffer and Early Z pass are different things. Assuming you are referring to latter one, you can disable Early Z Pass in project settings, but there are certain features, that will force Early Z pass on, even if it is disabled, such as forward shading and dbuffer decals.

On a side note, position only shader is exceptionally fast, and if you are getting slow pre-pass, quite likely you are doing something wrong.
