Hello,

After trying out Arma Reforger's Workbench I noticed their Forest Generator Components which you attach to any Spline Entity and it generates a forest in between the area If the spline is closed.

I want to achieve something like this in Unreal Engine but I have no idea where to start from? How can I Get the Area In Spline? And How do I populate the area with trees?

I want to populate the Area inside the spline that is marked with red marker.
