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"

[BUG] Cascade Warmup time breaks burst.

(also happens in 4.13 and 4.12)

If there is a warmup-time active (and set to 1 second or more), burst mode does not seem to work. This is either a bug, or intended.

In case of intended, there should at least be an option to override it that even with a warm-up time active burst should play when the particle is activated.

Depending on how your particle system is put together this wouldn't be considered a bug. If your burst particle emitter is set to Loop 1 time (meaning it just fires off once),and your burst particle's spawn time is set to 0, then this isn't a bug.

Let me explain this scenario.... I have a burst particle that spawns once at 0.00 seconds and has a lifetime of 1. I then set the particle system's warm up time to be 1 second. That means the particle system will start 1 second into the particle system's life. The burst particle has already played and died by the time the system has run through the warm up time.

To fix this you need to set the burst emitter's spawn time so that it starts after the warm up. In the example I gave I would set the burst to start at 1 second.

Let me know if that helps,

Ed
