Generators

RustEdit Pro

The nodes in the Generators category of the Terrain Graph's Add Node menu. Round sockets carry maps and square sockets carry single values. See Graph editor.

Constant

A flat field of one value.

Inputs

Input	Kind	Default	Notes
Value	Number	0.5	The value of every pixel. The slider goes from 0 to 1, but a wired value can be any number. Slider from 0 to 1.

Outputs

Output	Kind
Out	Map. The result this node produces.

Linear Gradient

Directional ramp from 0 to 1.

Inputs

Input	Kind	Default	Notes
Angle	Number	0	Which way the ramp climbs, in degrees. 0 climbs from the left edge to the right edge, 90 from the bottom edge to the top. Slider from 0 to 360.

Outputs

Output	Kind
Out	Map. The result this node produces.

Noise

Fractal noise. Rust style: Perlin, Simplex, Ridged, Billow, Cellular, Sharp, Jordan or Ridge Warp; Simplex and the kinds built on it match Rust. Unity style: Unity Terrain Tools' noise with all its settings, the same as the terrain tools' Noise filter and Noise tool.

Inputs

Input	Kind	Default	Notes
Style	Choice	Rust	Rust: Rust's own noise generator. Unity: Unity Terrain Tools' noise, the same as the terrain tools' Noise filter and Noise tool. Options: Rust, Unity.
Basis	Choice	Perlin	The kind of noise that each octave is made of. Options: Perlin, Simplex, Ridged, Billow, Cellular, Sharp, Jordan, Ridge Warp.
Scale	Number	800	The size of the biggest noise features, in meters. Bigger values make wider hills and valleys.
Octaves	Whole number	5	How many layers of noise are added, each finer than the one before. More layers add more small detail. Slider from 1 to 12.
Lacunarity	Number	2	How much finer each octave is than the one before. 2 makes each octave twice as fine. Slider from 1 to 4.
Persistence	Number	0.5	How much weaker each octave is than the one before. Lower values give smoother noise, higher values rougher noise. Slider from 0 to 1.
Seed Offset	Whole number	0	Change it to get a different random noise. Only used when Random Offset is on.
Amplitude	Number	1	Multiplies the result.
Normalize	On or off	On	On: the result is fitted into 0 to 1. Off: the plain sum of the octaves, the value Rust works with.
Warp	Number	1	Jordan and Ridge Warp only. How far each octave is pushed along the slopes before it. Rust uses 1 for Jordan and 0.25 for Ridge Warp. Shows only with some settings.
Damp	Number	1	Jordan only. How much steep slopes build up to quieten the next octaves. Shows only with some settings.
Damp Scale	Number	1	Jordan only. How strongly that build up quietens the next octaves. Shows only with some settings.
Offset X	Number	0	Shifts the noise across the map, in metres. Wire in a Seed Random set to Offset to use one of Rust's layer offsets.
Offset Z	Number	0	Shifts the noise up the map, in metres. Wire in a Seed Random set to Offset to use one of Rust's layer offsets.
Noise Type	Choice	Perlin	The base noise. Options: Perlin, Billow, Ridge, Value, Voronoi. Shows only with some settings.
Fractal	Choice	Fbm	How octaves of the base noise are stacked. Options: Fbm, Strata, None. Shows only with some settings.
Fractal Octaves	Number	8	How many octaves. A fraction blends toward one more. Slider from 0 to 16. Shows only with some settings.
Fractal Amplitude	Number	0.5	The first octave's strength. Each octave after is Persistence times as strong. Slider from 0 to 1. Shows only with some settings.
Fractal Persistence	Number	0.5	How much weaker each octave is than the one before. Slider from 0 to 1. Shows only with some settings.
Frequency	Number	1	The first octave's frequency. Each octave after is Lacunarity times as fine. Slider from 0 to 2. Shows only with some settings.
Fractal Lacunarity	Number	2	How much finer each octave is than the one before. Slider from 0 to 4. Shows only with some settings.
Strata Offset	Number	0	Shifts the bands. Shows only with some settings.
Strata Scale	Number	1	Higher makes more bands. Shows only with some settings.
Domain Warp	On or off	Off	Bends the noise by itself, for swirls and turbulence. Shows only with some settings.
Warp Iterations	Number	1	How many times the noise bends itself. Slider from 0 to 8. Shows only with some settings.
Warp Strength	Number	0.5	How far each bend pushes. Slider from -2 to 2. Shows only with some settings.
Warp Offset X	Number	2.5	Moves where the warp reads its noise. Change it for a different warp pattern. Shows only with some settings.
Warp Offset Y	Number	1.4	Moves where the warp reads its noise. Change it for a different warp pattern. Shows only with some settings.
Warp Offset Z	Number	3.2	Moves where the warp reads its noise. Change it for a different warp pattern. Shows only with some settings.
Translate X	Number	0	Moves the noise, in noise units of 512 metres. Shows only with some settings.
Translate Y	Number	0	Moves the noise through its third axis, which changes the pattern. Shows only with some settings.
Translate Z	Number	0	Moves the noise, in noise units of 512 metres. Shows only with some settings.
Rotate X	Number	0	Tilts the noise around the X axis, in degrees, which changes the pattern. Slider from 0 to 360. Shows only with some settings.
Rotate Y	Number	0	Turns the noise on the map. Slider from 0 to 360. Shows only with some settings.
Rotate Z	Number	0	Tilts the noise around the Z axis, in degrees, which changes the pattern. Slider from 0 to 360. Shows only with some settings.
Scale X	Number	5	Noise cells in every 512 metres across the map. Shows only with some settings.
Scale Y	Number	5	Stretches the noise along its third axis. The map is a flat slice of the noise, so this has no effect. Shows only with some settings.
Scale Z	Number	5	Noise cells in every 512 metres up the map. Shows only with some settings.
Flip X	On or off	Off	Mirrors the noise from left to right. Shows only with some settings.
Flip Y	On or off	Off	Mirrors the noise along its third axis. The map is a flat slice of the noise, so this has no effect. Shows only with some settings.
Flip Z	On or off	Off	Mirrors the noise from top to bottom. Shows only with some settings.
Random Offset	On or off	On	On: every Noise node gets its own random shift from the graph seed and Seed Offset. Off: only Offset X and Z move it, as in Rust.
Size	Choice	Height	Which map's resolution the noise is made at. Rust makes each map's noise at that map's own size. Options: Height, Splat, Biome, Topology.

Outputs

Output	Kind
Out	Map. The result this node produces.

Position

Each texel's place on the map, in metres or from -1 to 1, at Rust's pixel centres.

Inputs

Input	Kind	Default	Notes
Size	Choice	Height	Which map's resolution to make the positions at. Options: Height, Splat, Biome, Topology.

Outputs

Output	Kind
X	Map. Metres across the map.
Z	Map. Metres up the map.
U	Map. Across the map from -1 to 1, 0 in the middle.
V	Map. Up the map from -1 to 1, 0 in the middle.

Radial Gradient

Concentric falloff from a centre point.

Inputs

Input	Kind	Default	Notes
Center X	Number	0.5	Where the center is across the map, from 0 at the left edge to 1 at the right edge. Slider from 0 to 1.
Center Y	Number	0.5	Where the center is up the map, from 0 at the bottom edge to 1 at the top edge. Slider from 0 to 1.
Radius	Number	0.5	How far from the center the value falls to 0, in map widths. 0.5 reaches the map edges from the middle. Slider from 0.01 to 1.5.
Falloff	Number	1	The shape of the slope. 1 makes a straight cone, above 1 a sharp peak, below 1 a round dome. Slider from 0.01 to 4.
Invert	On or off	Off	Flips the values: 0 at the center and 1 at the radius and beyond.

Outputs

Output	Kind
Out	Map. The result this node produces.

Voronoi

Cellular / Worley noise.

Inputs

Input	Kind	Default	Notes
Scale	Number	500	The size of the cells, in meters. Bigger values make fewer, larger cells.
Output	Choice	F1	Which distance makes the value. F1 gives rounded cells, F2 - F1 gives sharp cell borders. Options: F1, F2, F2 - F1.
Invert	On or off	Off	Flips the values, so high becomes low. With F1, the cell centers become peaks instead of pits.
Seed Offset	Whole number	0	Change it to get a different random pattern of cells.

Outputs

Output	Kind
Out	Map. The result this node produces.
