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"

Foliage culling

For some reason culling won't work for me. I add a static mesh in the foliage mode panel and set it to start culling at 1 and stop at 50 for example (i've tried all kinds of distances) and nothing happens. It's not that it doesn't fade, it doesn't cull them out at all, from any distance.

I've tried different cluster settings as well, at the moment 256 instances and 1024 cluster radius but nothing works.

Would really like some help with this.

Thanks in advance!

Culling only works when you click Play or when you turn the Game Mode on (press G in the editor :) )

Oh, I'm an idiot for not trying that. Thanks! Is there any way to have it "on" while in the editor without having to use game mode? I'm building an enormous map so I'm sure it'll start lagging without culling while building.

I'm not in front of my UE PC now so can't check it, but try and have a look in the View menus.

Also what I found is that the foliage geometry itself isn't that expensive (assuming you're not using super dense high poly meshes that is), but having the Cast Shadows on them enabled drains your resources rapidly! For development I would suggest turning it off :)

Thanks :) I'll see if I can find it. Didn't think of turning of shadows while working either, thanks!
