@lisyarus The irony is we had really nice antialiasing of the line itself because they were generated as an SDF. But the features that generate them weren't stable enough, so...
The heightmap is based on just several layers of fractal perlin noise. Mountains are fractal ridged noise (= 1 - abs(2 * perlin() - 1)).All computed with automatic derivatives using dual numbers, which I use to place stone/grass, etc.
