In all tutorials i watch and on all the pictures is see about ue4 foliage, there are settings below the foliage. I can’t figure out where they are or how to get them. Pretty sure the answer is quiet simple. Thanks to all of you in advance

I already tried that but nothing shows up
You need to have both. Your foliage item hightlighted and those arrows pointing downward…
thank you soooo much :’)
