Foliage brush and speed tree?

melviso

I understand that speed tree doesn't work with foliage tree in Udk. Does this work in Unreal engine 4?
Also I am trying to make a prefab of the grasses I made with speedtree. The prefab seems to be empty whenever I drag it from the content browser into the level.

Guys I need some help.I used foliage brush to paint in a clump of glass mesh I created in Maya over a huge landscape in udk.Problem is its taking very very long for the lightmass to build.

Am I better off using speed tree for the grass?I noticed I can't make a prefab of a bunch of duplicated grasses I created on the .
Pls any help would be appreciated.This is urgent pls.

I seem to recall some recommendations from Epic about excluding grass from lightmass, or using different lighting settings for grass.
