Grass Brush

The Grass brush generates random columns of voxels with a constant distribution; similar to grass or small plants.

The height of the grass is affected by the brush height and the color of the voxels is determined by the selected colors in the palette.

This shader is similar to the Grass Fit shader, which it is applied to the entire volume.

Parameters

Parameter	Description
Direction	When `0`, line extends upwards. When `1`, line hangs downwards
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. `50` is a evenly-distributed growth. Higher or lower values will overgrow or stymied the growth, respectively
Seed	Global seed

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.)
