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"

Niagara particles in sequencer, issues with packaging

Hey there, I'm having a particularly hard time trying to get a project to final build, as my particles are not owrking. there's quite a few different particle effects running throughout our project, and due to the nature of our final output (a set-length VR music experience) we have opted to animate all of their properties via Sequencer. This isn't an issue in editor, everything looks great, and functions as expected. However, running as a packaged build seems to delete or ignore these animated properties. Effects still follow transform animations, but all of their parameters just stay as their level-specified values.

It feels like I'm missing something incredibly simple about this process, but working a Niagara/Sequencer pipeline is new to us (and I would imagine most).

Any help or illuminating inquiry would be much appreciated.

Current work-around: using curves within the Niagara system, against emitter looped age. Not the most elegant, but has gotten us moving again. Unfortunately it's not tied to the timing on the sequencer (so no previewing for the artist) but at least they can pump out some animations and watch them down.

Same problem here. All Niagara related keyframes are ignored

Same here, Using life cycle of niagara in sequence, but only work in editor. After packaging, niagara is out of sequence control !!!!!!!

Having the same exact issue with our VR project... Is there anything that needs to be moved over to the packaged build in a plugins folder there?
