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"

Bad Perfomance With Masked Materials

Hi, i made an effect with a sphere mask that covers my entire level and fades in the opacity of the materials as it gets bigger. I want to simply reveal the opacity of objects as i walk around them. The interior of the sphere has 1 opacity and the exterior 0. I came to a point where there is a big performance issue with overdraw in some big levels. Ticking on ''Mask material only in early Z-pass'' gets rid of shader overdraws in Shader Complexity view mode completely, which should be ok, right? But the performance is the same around 65 fps, with opacity full 1 it is around 80. Do i miss something here? Is there another method which doesn't have this kind of impact on fps?
