Region Strata

Overview

Generates strata-like regions with undulations, cracks, and steps. It adds geological irregularity to the regular bands of region_bands, providing a base for cliffs, rock walls, soil cross-sections, or dungeon walls with mineral veins.

Usage tips

• The go-to recipe for a cliff or cross-section is region_strata(Horizontal) → region_fill, using a different earth tone for each layer, then region_border for the lines between layers.
• Think of texture as two controls: waviness for the undulation of layers, and break_count / break_jitter for cracks. Zero waviness with many breaks creates blocky masonry; high waviness with few breaks creates natural strata.
• For ground in a side-scrolling background, enable wrap_x to make it repeatable.

Related nodes

• region_bands — regular bands without cracks
• region_fill / region_border — fills and boundary lines
• region_merge_small — clean up fine fragments
• region_noise — use when you want non-directional variation

Directly generates a strata-like RegionMap with cracks and interruptions at the final size. It is suited to rock walls, cliffs, soil cross-sections, and mineral layers.

Key parameters

This node is better suited to rocks and cross-sections than Region Bands.

When mask is connected, strata regions are generated only inside the active mask area and the outside is treated as OUTSIDE. Pixels where lightness * alpha >= 0.5 are active. An arbitrary mask shape takes priority, so wrap_x / wrap_y are disabled in the output while a mask is connected.

Because this node creates directional surfaces, direction has a large effect on their distribution. Use Region Cells for evenly divided cells, Region Bands for regular bands, or Region Voronoi for point-centered surfaces.
