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 particle continu ?

Why does the type of ribbon appear to be not subject to the "lifetime" module like other types of particles? And if there is no way to manage the "lifetime" module how to bypass to create an "infinite" ribbon otherwise ?

The only example that comes close to the desired effect that I know does not work for me, here's the link: https://forums.unrealengine.com/showthread.php?6000-Light-Cycle-Particle-Trail

Put lifetime at zero for the basic particles it works to make them infinite, but not for the ribbon type, I had already tried

Oh wait, thats right.

Its a bug/limitation of ribbons since it allocated the amount of verts needed on spawn, with an infinite lifetime it only gets the max amount of the trail count which generally is 50 I think. The problem is, if you increase this number to something really high it can crash or at least extremely slow down your computer.

So its not wise to use infinite ribbons, but just give them a long trail and quite a high max trail count. (watch out with values higher than a few 1000)

Edit: also doesnt work, so my best suggestion atm is to give them a rather long lifetime but do fade them out after that longer lifetime. performance and all.

I happen to have found another answerhub post which is somewhat related: https://answers.unrealengine.com/questions/524901/bug-ribbons.html
