Animate landscape heightmap w/ noise and blueprint

Hi folks, I’m using a blueprint brush with a noise material to drive the height map of a landscape as in this tut.
The idea is to get an erosion time lapse effect, so I’m trying to drive the seed parameter of the noise during run time with an Event Tick through a dynamic material instance, but does not seem to be working.

Question(s) is, is that at all possible? Should I use a different approach? My camera is fixed in space, so it could be a large mesh instead of a landscape object if that makes a difference. I was looking into Virtual Heightfield Mesh, although I wouldn’t be able to scatter objects on it with that method.

Any clues or leads are welcome, and I can provide more details if didn’t explain it clearly.

Thank you.

were you ever able to figure out a workflow? I’m curious on this idea as well.

I ended up using a Material Parameter Collection to drive the displacement of every material with the same settings. Took a bit of finessing normals, and it’s not very scalable plus you don’t have any collisions but here’s a video

I know I’m late, but great job on this!
