Terrain Folding without the Fold Node

This is a very simple yet effective method for creating terrain folding without using the Fold node. The basic concept is to use a highly warped noise to cut grooves in Voronoi.

Create a highly warped Perlin.

Use the Perlin to mask a Voronoi (Form P, no Warp, Dual on if you prefer)

Displace with a few iterations for nice long stretches (High Quality off), and then clamp it to get the height down.

Erode with default settings.

The main image is with a bit of snow added, and Texture + Satmaps (both using Navajo Sandstone presets).
