Tried following the tutorials at: http://docs.unrealengine.com/latest/INT/Engine/OpenWorldTools/ProceduralFoliage/QuickStart/2/index.html
But when I go to select the HillTree_02 mesh the editor says Loading HillTree_02 72% and just stays like that for hours. Any ideas on a fix?
CPU at 29% and memory at 42%
