Always found it weird you couldn't do a minimum altitude limitation on stuff in terrain nodes, especially strata, so I came up with this simple setup for strata. It's bug prone but works for simple strata accents.
How come, no altitude restraints?
I guess I could have mentioned final position works, but not if you then want to warp the strata. Perfectly straight strata bothers me. Lol Though it seems you can't even warm the strata without doing a redirect/warp on the terrain it seems upon further tinkering.
