Grass Brushes

The Grass brushes generates randomly protruding lines of voxels with a constant distribution; similar to grass, small plants or similar surfaces. The height of the grass is affected by the brushes height.

There are two shaders, grass and grass_inv, that are functionally identical except grass protrude upwards and grass_inv extrudes downwards.

Parameters

Mode: Color mode (see below)
Density: Size of the area in which a line should be generated. Increasing density will increase the spacing between lines.
Growth: Affects the growth of the lines. 0.5 is a fairly evenly-distributed growth. Higher or lower values will overgrow or stymied the heights, respectively.
Seed: Random seed
Color A: First color index
Color B: Last color index

Setting either of the colors to 0 will also result in empty voxels.

Mode

There are 4 distinct color modes for generating voxels, as outlined below:

Mode: `0`	Mode: `1`

The color of the line is dependant on its height.	The color of each voxel in the line is chosen at random.

Mode: `2`	Mode: `3`
The color of the line is chosen at random.	The color of the line is a gradient between Color A and Color B (regardless of height.)
