Vegetation scatter, spline fill, texture map population

I’m a landscape designer and from the start I’m so impressed with possibilities of ArchViz with UE4.
I work on many software to make Viz for my clients and I know many useful tools that speed up process od creation.
When we think about vegetation population/distribution/scatter I see that there are no two useful tools that should be made In the future.

  1. Population with the texture map on imported/created mesh surface. Something similar to carbon scatter ( It is simple but very powerful tool that I use in 3ds max. You can make color grading on image and that it is few minutes to distribute 3d plants where they should be in project.
  2. Distribution with closed spline. For fast visualization I use Realtime Landscape Architect. It is simple software but have very good tools. Especially distribution fill in closed spline (
