FoliageInstances driving by texture or LandscapeGrass without landscape?

I need something to scatter static meshes on moving actor. Scattering by texture.
And then I need to remap this texture in game, and scatter will rebuild in real time
I want total procedural creation, ideal in material, like LandscapeGrass but by texture from this material, and when I change material instance parameters, scatter will rebuild.
is there anything build-in for this?
or I need to build it in actor event graph, read texture from material and rebuilding scatter?

thanks for answers and sorrrrrry for my English.
