Great, thanks for being so quick. 
EDIT: By the way, is there any way to make the forest generator generate in the editor? Like not in-game. Would be cool.

I’ve tried that at the beginning, but it’s not possible to spawn actors via construction script + it would need to run a lot of logic to immediately generate billboards, etc… And without billboards, a lot of trees would lag the editor, since they’re not a regular static meshes. That’s why there’s a workaround with ‘Tree’ & plant pillars to visualize where they’ll spawn.
However, with the new 4.13 scene capture component mechanics it might be possible to implement in a different way, allowing for in-editor forest generation (probably using Child Actor Components and generating billboards in-editor), but I’m not sure yet if this will work. I’ll keep that in mind.
