Erode

The erode shader randomly removes the surface voxels from your volume based on a 3D noise texture, giving the impression of erosion and damage.

This shader only removes voxels that match the selected colors from the palette.

Parameters

Parameter	Description
Threshold	Limits the erosion to voxels with a certain number of neighbours. See below for more information.
Scale	Size of erosion texture. Larger values producer smaller clusters of erotion.
Seed	Global seed

The seed is automatically randomised on each iteration.

Threshold

Each voxel has 26 neighbouring voxels:

• The default Threshold of 9 will include voxels with at least nine empty neighbours (for instance, the outside layer of a wall).
• A Threshold of 1 will include any voxels with at least one empty neighbour, which includes all voxels besides those surrounded by other voxels.

Threshold: 1	Threshold: 18

Scale

Scale: 3	Scale: 6	Scale: 20

Seed

The Seed affects the generation of the 3D noise used to erode the volume. However, unless you update the Seed each time you run the shader, the same texture will continue to be used. However, when the shader is run with Iterations, the Seed is updated automatically.
