Hi there, here are a few environments I've been experimenting with using Blender 3.0 and Scatter 5 addon. I'm loving the level of control and variety you can get with the addon. Used a lot of vertex groups and vertex color to specify where to put the assets using the addon. The rest of the assets like rocks or any other props are from Megascans.

In the third image I decided to make a mix between the Scatter Tool with Megascans grass assets and the biomes assets in the addon.

Maybe I can make a tutorial later on to show how it works.

Regards, Alberto
