Possible to use landscape material on custom landscape mesh?

Before I start looking at vertex painting I was wondering if there is any way to get a landscape material working on a custom landscape mesh (one that isnt using the standard landscape system). Thank you for any help!

A ‘landscape’ material is just a regular material but used on a landscape mesh in the system Epic sets up. The only really landscapey-thing is the use of the named layer-samplers, those won’t work outside of the landscape-mesh system in unreal.

If you remove those, anything past that, vertexcoloring, vertexnormalWS, time, etc will still work b/c at that point it’s ‘just a material’ on a mesh.

The landscape system does some other stuff like LODing and whatnote but otherwise it’s material is like any other material (per what I said above).
