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"

Particle absolute time unable to go over 1 second

Whenever you create a curve for any initial modifier for a particle system, it's supposed to be operating on absolute emitter time, not on per-particle lifetime, but the absolute time is apparently broken as the effect will just stop once it reaches one second.

For example, if you try to use an initial size modifier to have your particles start spawning small and new emissions will grow larger over time, the scaling will stop after the first second even if you set it to something higher.

It seems like there's some bugs with the absolute time modifiers for particles cause they simply don't work after the first second. I've tried a lot of trial and error but nothing is helping.

Someone else had the same problem here, but I don't think a fix was ever made for it.

I'd like to make it clear that this isn't something that can simply be replaced with a lifetime based modifier. With this broken you're completely unable to make the system fade in or fade out over time.

Hi Chaofanatic -

This does appear to be a regression of particle behavior. I have added a new Report in as UE-21246 and will let you know as we investigate a solution.

Thank you for your help and report -
