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"

How do you loop through a particle system and place particles in specific positions?

Is there some sort of array of all particles in a particle system that i can access and use a for loop on? i need to give each particle a unique position. I've searched all over and found nothing about how to do this, the only thread i found about this was about doing it from an image and i didn't really understand how they were accessing the particles and setting their positions. Could anyone explain how to get the individual particles and place them with vectors/math?

as far as i know you can't get an instance to every particle in a particle system, it would be extremally heavy, your computer would die screaming for help. are you sure you really need to do it? if you tell me what exactly you want to do maybe i or someone else can help you achieve your goal.

I would be interested in this as well because I need to place a bunch of labels inside spheres inside an actor. I need about 17000 labels.

well, I'm attempting to create a procedural spiral galaxy map and i thought that a particle system would be the best suitable option, however i don't think it's possible to create the spiral structure except through some coding, or am i wrong in thinking that? i would really appreciate some help in how i'd go about doing this.

Edit: i found this thread https://forums.unrealengine.com/showthread.php?77214-Free-Particle-Editor-Module-for-Spiral-Galaxies but it doesn't seem to work for the latest unreal version or something. i made a post in that thread that's under approval or something atm. Just wanted to leave this edit here if anyone here can help me and for posterity.
