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"

Deactivated particle systems take a lot of GPU performance.

Why do deactivated particle systems take a lot of GPU performance? I need a lot of deactivated particle systems, which are sometimes getting turned on. Should I be deleting and spawning new PS? But It does not sound like a much better solution.

Product Version: UE 4.12

hmm thats odd. normally deactivating an emitter should not have such an impact. what are you deactivating? a 1000 drawcall beast?

can you give us (much) more information about the systems? How are you deactivating them?

we will need way more info to give advice.

Sorry for delay. It actually was a weird memory leak. Editor suddenly consumed 14GB of RAM and generally this was the case of an enormous slowdown.
