BP Draw to Render Target on Landscape?

From what I gathered after watching the BP Draw to Render Target tutorial stream, it seems as though the blueprint handling the drawing behavior needs to reference the object that is being drawn on, so I’m wondering if it’s possible to do this to a landscape? I’d (ideally) like to use the feature to draw out R G and B marks on the landscape to create different dynamic alpha masks to lerp different landscape diffuse textures (and also mask out stuff like landscape foliage) so I could do stuff like clear out grassy areas, replace them with dirt areas, all at runtime. Is this something that’s possible?


Id like to know too.
