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"

Are there a max number of emitters for cascade?

I am trying to create a fairly complex particle system and have created 36 emitters in cascade. I created these fairly successfully but whenever I try editing anyone of the modules, the program immediately freezes (this is even if I try to reduce the amount of particles). I checked my Ram usage while this is happening and it is steadily between 1 and 3 GB of RAM. I also have had the viewport off the entire time to ensure that wouldn't slow it down. Actually running the particle system in the level works fine with no lag too. My system also has 32 GB of RAM so I feel like this shouldn't be an issue, especially when Unreal is only using 2 of them on average.
