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 system spawned by sequencer does not emit

I've tested this in a minimal project and it doesn't seem to work. I add a particle system to sequencer and convert it to spawnable. The particle actor icon appears in the editor upon spawning but does not emit.

Hey hynzla,

In your sequence make sure to add a particle toggle track and add a key with the value "activate" in your timeline. By default particle effects spawned by sequencer don't activate on spawn. If that isn't working for you let me know and I will continue investigating.

Good luck!

Thanks Ed, I had the same issue and that fixed it for me!

I have a particle system that's attached to my player pawn as a component. The solution posted by Ed works for me in this case, also. Thanks a bunch!

The full list of steps is:

  1. Expand the character's track.

  2. Click on + Track next to the character (not the green one at the top of Sequencer).

  3. Find your Particle System Component and add it as a track.

  4. Add a track for this PS Component. Select the Particle Toggle Track as Ed mentioned above.

  5. Key an "activate" state in at some point in the Sequence.

  6. Finally, right-click inside Sequencer on the Particle Toggle Track you just created. Select Properties and edit the "When Finish" item to display "Keep State" (instead of "Restore State") in order to keep the PS activated once the Sequence has finished playing.

  7. Voila!
