Foilage tools / difference between Foilage Type and Static Mesh

Hello All,

I have question about the Foilage tools

I have several rocks in my foilage tools, some are set to Foilage type and others are set to static mesh.
Some come from quixel guess there are setup with LODS and there for come in as Foilage_Type.

Whats the difference? and is it better to use the FoilageType.




If you drag static meshes into the foliage tool, once you’ve finished configuring the placement, you can save this config as a foliage type. This foliage type can later be loaded and used again.
