How to attach a Dynamically Generated CustomBrush_Landmass to a landscape

Hi everyone,

I have a script that can generate actors/meshes, was wondering if landscapes baking of landmass brushes could be done prior to level loading? That would be the end case but as an intermediate step could just in editor randomly made landscape_custombrushes be added to the landscape?

Right now I have them being made but they aren’t affecting the landscape - when I manually drag it in they work as intended.

I am looking for similar solutions. Any update on that? Can modify landscape before loading it into the game?
