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"

Emitter Duration not being respected.

My Emitter Duration in the Required field of the emitter is set to 5sec. I have a Cylinder that travels 200units in Z (up) over 5 seconds using a constant curve. I am unable to get the emitting Cylinder to travel its full height over 5sec. It seems to stop at 1sec. Is this a known bug? Am I missing a step?

Thanks in advance.

Can anyone help me with this? Are you able to make a Cylinder Emitter travel in up Z over 5sec? If so how did you do it? Or is it a bug?

I think you are hitting same issue I had reported in 4.8: https://answers.unrealengine.com/questions/259341/48-particle-system-regression.html

This isn't a helpful answer, but it's a bug that's been reported a few times here, and has been plaguing Cascade for years - any curve that uses the emitter time (instead of particle lifetime) as the X axis doesn't read values after X=1 second. So as a user, I have no ability to animate things like initial velocity/size/color/alpha, emission rate, location offset, etc past one second.

I've just made a new post about it, because it's driving me crazy consistently, and I can't believe it hasn't been corrected yet: https://answers.unrealengine.com/questions/512338/curves-in-cascade-using-emitter-time-do-not-read-p.html
