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"

Partical System size help

I have quite a large level and was wondering how to make my partical system cover the whole map. I made a simple snow system but I cant seem to get it large enough to cover the entire terrain. I tried setting the fixed bounds and i also tried setting my own size in the bounds menu but neither worked.

That would probably be way too much processing. What most developers do is put a particle system around the player so the snow follows them around. Like the person who is so unlucky that a rain cloud follows them wherever they go: they always think it's raining.

@Jin_VE is right. It would be best to have a particle system that follows each of your players. Check Landscape Mountains project that Epic provides. They've exactly implemented this feature that you want.

I've never done it myself, but I would think the trick is to make the particles spawn so it gets denser further out. I think that's how fog works too. Otherwise you'll be able to tell it's just a fixed volume around the camera.

Althought the snow would move with you, i have an idea that attaching it to the player is the way its usually done efficiently. You could try uaing particles that dont follow the player but use world space instead, that would help if you have enough spawn rate.

Yeah. You can tell the PS to not inherit velocity.
