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"

Spawn a set of particles at predetermined locations.

I wish to spawn a set of particles, essentially points, according to the locations stored in a FVector array. What happens to it post spawn is nothing. Every point should just be a point hanging in 3D space. If the lifetime is infinite or if I respawn them every n seconds is of no concern.

As a side question, is there a way to render a 200000 point pointcloud in UE4? I so not want 200000 meshes being rendered as I can predict that reduces UE4 to Powerpoint.

Thank you in advance.

Were you able to do this? I need to render 100,000 particles. I am using the DrawDebugPoint() function, but it runs at about 21-22fps. I would like to use the Particle System with GPU sprites.

I tried, but I failed. I might look into this again when I get the time.

One way seems to be spawning all particles in the same place and using a material offset to place each particle.
