Textures¶

The Texture operation paints a terrain layer inside its mask.

Terrain Layer

The terrain layer to paint. It's added to the target's terrains automatically if they don't have it yet.

Opacity

How strongly it's painted, from 0 to 1.

How painting works¶

At each point, the terrain layer moves toward full coverage by Opacity times the mask strength. Where both are 1, it replaces what was painted there; lower values blend it over the existing paint. The other terrain layers fade in proportion, so the layers always add up to full coverage.

Texture operations paint over each other in the order stamps are applied: stamps lower in the Hierarchy, later layers and later operations in a list paint on top. Everything starts from the painting stored in the target's base.

Paint rock on steep slopes¶

1. Draw a stamp outline over the area to paint.
2. In the layer's Mask Composition, below the Spline Area, add a Terrain Slope fill with Mode set to Multiply, and set its Slope Degrees Range, for example from 35 to 90.
3. In Stamps, set the operation to Texture and pick the rock Terrain Layer.
4. For a softer transition, turn on Modulate Alpha By Incidence, or add a Noise fill in Multiply mode to break up the edge.
