Node reference

Every node in the TerrainForge catalog, with its ports and every parameter's default and range.

This page is generated from the plugin's own node catalog, not written by hand. Each native node carries its catalog entry in its source file, and the editor's node library, the node inspector and the agent tool ListNodeTypes all read that same entry. The labels, descriptions, ports, defaults and ranges below are copied from it.

To regenerate after the catalog changes, from the root of the wiki repository:

node tools/export-terrainforge-nodes.mjs <path to the TerrainForge plugin folder>
node tools/gen-terrainforge-nodes.mjs

The first reads the source and writes data/terrainforge-nodes.json; the second writes this page from that file.

Every node runs natively. There is no node that needs another program or a service. Where a node has a GPU kernel and the Compute setting allows it, part of it runs on the graphics card; the result is checked against the CPU version. See GPU compute.

Reading the tables

Ports carry one of four kinds of data: elevation (a heightfield in metres), mask (0 to 1), colour (sRGB, for display) and RGB data (linear packed masks). They are not interchangeable: validation refuses a link between different kinds.
An input marked optional can stay unconnected. A required input must be connected before that branch can be previewed or built.
Distances and heights are in metres, areas in square metres, angles in degrees, unless the label says otherwise. Positions are metres from the map centre, X east and Y south.
"New nodes start at" marks a parameter whose default for a new node differs from the value an older saved graph keeps. Saved graphs are not changed by an update.
Runtime only marks the per-node compute choice (auto, cpu, gpu). It decides where the node runs, not what it computes.

Category	Nodes	What is in it
Generate	5	Nodes with no terrain input: a starting heightfield from a file, noise, a ramp or a constant.
Landforms	11	Placed features in world metres: ranges, peaks, canyons, volcanoes, islands, dunes, plateaus, lava and rock strata.
Layer	3	Ways to combine two or more heightfields.
Shape	21	Filters and deformations of one heightfield. Most take an optional mask that limits where they apply.
Simulate	18	Erosion, weathering, glaciers, geology and snow. These are the expensive nodes, and the ones the GPU speeds up.
Water	11	Rivers, lakes, drainage, floodplains and coast.
Select	17	Nodes that turn a heightfield into a mask, or combine masks. Several of these feed biome rules and paint layers.
Color	7	Colour and packed-data outputs for materials. They do not change the terrain.
Export	1	The node whose terrain becomes the build output.

Erode (particles + sediment)

Type Erode.

Rain drops run down the terrain, erode where they carry less than they could and settle where they carry more: channels and gullies cut in, fans, filled hollows and floodplains build up. Runs coarse to fine (valley-scale channels, then gully-scale rills); fresh sediment relaxes to its angle of repose. White resistance erodes no rock; rainfall scales the number of drops.

Erosion detail

Type ErosionDetail.

Carve branching, flow-aligned gullies into slopes without a simulation. Stripes run downhill and each finer octave follows the walls of the coarser gullies, so they branch like tributaries. No detail on flats or in channels; deeper in hollows, shallower on hard rock. Strata and joint sets act as resistance, not as added height. Gullies start only where enough area drains down a steep enough slope (channel heads), never point into closed depressions, and leave a ring around small lakes. Outputs the gully and ridge masks and the resistance used.

Geology (rock volume)

Type Geology.

A 3D rock volume under the terrain: dipping, folded and faulted beds of hard and soft rock, with joint sets and fault damage zones. The terrain passes through carrying the rock, and Erode samples it at the eroding surface as it cuts down, so hard beds stand as ledges, ribs and benches and joints steer gullies. Resistance is the rock at the input surface (white = hard) for any node with a resistance input; bed and joints show the hardness and the weak zones, layers numbers the beds.

Glaciate

Type Glaciate.

Carve the terrain with glaciers at their maximum extent: steady-state balance-flux ice above an equilibrium-line altitude, abrasion that scales with sliding speed (U-shaped troughs, hanging tributary valleys, overdeepenings), cirques with tarns at glacier heads, lateral and terminal moraines, then a post-glacial river pass. Physical units: metres and years. Large-scale work runs on an internal ice grid; fine detail outside the ice is kept.

Gullies (fine incision)

Type Gullies.

Cut real gullies at full resolution: water is routed locally, channels incise where enough area drains down a steep enough slope (the channel head sets the gully spacing, tens of metres), and hillslopes between them are rounded by soil creep that speeds up towards the critical slope while cliffs stay sharp. Gives the 8-64 m relief of real mountains instead of uniform noise. Runs tile by tile on big terrains. Optional resistance (hard rock incises and creeps less) and mask. Outputs the terrain, the channel mask and the incision depth.

Landform (uplift and rivers)

Type Landform.

Grow mountains from an uplift map: rivers cut into rising rock until erosion balances uplift, which forms dendritic valleys, spurs, cols and varying crest heights. Implicit stream power with deposition, lakes that trap sediment and hillslope diffusion, in metres and years. White uplift rises at the given rate; white resistance erodes less.

Inputs: terrain (elevation, optional), uplift (mask), resistance (mask, optional), rainfall (mask, optional)

Rockfall & scree

Type Scree.

Rock faces steeper than the release angle shed debris. It runs down the steepest path, stops where the slope eases below the scree angle or its energy line flattens below the run-out angle, and settles into talus cones under gullies and aprons along cliff feet. White resistance keeps rock from releasing (parallel: resistant rock stands up to the resistant release angle and its debris rests at the coarse scree angle); black mask protects cells. Closed edges conserve volume. Resolution independent. Parallel execution moves every column at once (GPU-capable) and settles the fresh debris at its angle of repose.

Snow

Type Snow.

Form-aware snow cover: a snowline in metres or as a fraction of the relief, lower on shaded faces, scoured from wind-exposed ridges and collected in lee slopes and hollows, then redistributed by avalanches so steep faces shed their snow into couloirs and cones.

Valley fill

Type ValleyFill.

Fill eroded V valleys with sediment where their drainage area is large: broad flat floodplain floors that widen downstream, rise gently to the valley walls and stop there. Deep closed basins stay lakes at their spill level, small hollows stay as they are, other basins fill with sediment that drains gently towards their outlet. Only raises the terrain.

Water

Rivers, lakes, drainage, floodplains and coast.

River path

Type CarvePath.

Graded preserves the original spline trench. Alluvial adds bounded bend migration, terrain confinement, pool cross sections and sediment-limited inner bars. It is a kinematic model, not 2D hydraulics. Guides pin the bankfull course; tributary joins and lake shores also pin the wet course. End at a world edge, lake or another river within Junction snap. Cutoffs and braiding are not simulated. In Alluvial, waterWidth(s) controls the channel; width and slot apply only to Graded.

Floodplain and terraces

Type Floodplain.

Flatten valley floors next to rivers into floodplains at the bankfull level, with natural levees and back-swamp wetlands, and cut river terraces above them.

Type FlowRoute.

Analyse drainage without changing the terrain. Routes water with D8, random D8, multiple flow directions or D-infinity over filled, carved or basin-linked depressions, and exports flow, channels, height above drainage, wetness, lake depth, drainage basins and stream order.

Sea and coast

Type Sea.

Floods the terrain below a sea level from the map edge and shapes the coast. Exposed rocky shores retreat into wave-cut platforms below cliffs; gentle shores get Dean equilibrium beaches out to the closure depth with a berm above the waterline. Exposure comes from the open-water fetch towards the swell. All lengths are in metres, so the coast keeps its size at every resolution.

Operation `mode`	`mix`	`mix`, `multiply`, `screen`, `overlay`, `soft_light`, `hard_light`, `add`, `subtract`, `difference`, `min`, `max`
Opacity `amount`	1	0 to 1, step 0.05
Blend space `space`	`linear`	`linear`, `srgb`

Adjust color

Type ColorAdjust.

Hue rotation, saturation, lightness and gamma for sRGB colors. A mask limits adjustments; packed data is a separate type.

Inputs: color (colour), mask (mask, optional)
Outputs: color (colour)

Parameter	Default	Allowed
Hue shift (°) `hue`	0	-360 to 360, step 5
Saturation scale `saturation`	1	0 to 3, step 0.05
Lightness shift `lightness`	0	-1 to 1, step 0.05
Gamma `gamma`	1	0.1 to 5, step 0.05

Pack RGB masks

Type RGBMerge.

Pack R/G/B masks as linear data. No gamma conversion. Each channel can optionally be enhanced; leave None for calibrated masks.

Inputs: r (mask), g (mask), b (mask)
Outputs: packed (RGB data)

Parameter	Default	Allowed
R enhancement `enhancer`	`none`	`none`, `autolevel`, `equalize`
G enhancement `enhanceg`	`none`	`none`, `autolevel`, `equalize`
B enhancement `enhanceb`	`none`	`none`, `autolevel`, `equalize`

Unpack RGB masks

Type RGBSplit.

Recover the exact R/G/B masks from packed linear data. The average output is an arithmetic mean. Color textures are a distinct type.

Inputs: packed (RGB data)
Outputs: r (mask), g (mask), b (mask), average (mask)

No parameters.

Export
