Unity Terrain: add an outline texture to certain terrain layers

Unity Engine
1

Hi, I’m searching for a way to add a outline texture to certain terrain layers.
I want to create a world where certain layers can have a outline, like a stroke.

I know this is a quite advanced topic and I’m quite new to unity’s terrain system so my Ideas so far would be:

  1. I try to create it via using the “splat map” and the “height map” and generate a mesh on top of it. Which sounds complicated but would probably generate the best outlines.

Or is there any asset that lets me paint thin borders textures around it?

Any help appreciated

I think the custom pass might be help. GitHub - alelievr/HDRP-Custom-Passes: A bunch of custom passes made for HDRP
