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"

Ribbon particles randomly shoot away [SOLVED]

Hello, I am experimenting with particles in UE4 and I have been trying to make a firework. In current form it looks like this

alt text

However, when the system is getting to near its end time, some of the ribbon trails start jumping off to other sparks briefly and then vanishing, making brief random streaks across the view, often after the particles between which it jumps have already disappeared. Below two such streaks are shown. alt text

I have tried tinkering with a lot of different parameters and I still cant get these things to go away entirely. Any help would be much appreciated.

For me it was a totally different thing that solved the problem. Under "Ribbon Data" -> "Tangent Recalculation Every Frame" need to be ticked.

Ok, after several more days of experimenting I seem to have got it: the emitter for the trail particle needs t obe set to one loop only (instead of the default infinite). That solved it for me.
