Landscape export Weightmap to RenderTarget doesnt work

Hey everyone,
I am trying to use Landscape Export Weightmap to RenderTarget Node in an Editor WIdget Blueprint.
I want to make a non runtime tool for myself to be able to write to a mask in editor with the landscape painted material.
After some digging it looks like this is the exact functionality that exists with these nodes , but it doesnt produce anything.
The similar node - Export Heightmap to RenderTarget , seems to work correctly
Here are the nodes pretty simple - what am I missing ?

looking at the UE5 EA2 source code, and to this day the c++ function for this BP node does nothing and just returns false

any plans to implement this?
