Node Reference Overview
Use this section when you need lookup material rather than a guided lesson. The reference is organized around Gaea's node library, with supporting maps and integration-specific reference pages where they are useful.
If you are learning how to build terrains, start in Using Gaea first. If you already know the node, category, or output you are looking for, this is the faster place to work from.
Start Here
Use the reference when:
- you want to look up a node's purpose, properties, or usage notes
- you are comparing similar nodes inside a family
- you need a fast route to node videos or examples
- you are checking bridge-specific node reference material
Main Areas
Node Map
Start with Node Map when you want a visual or structural overview of the node library before opening individual pages.
Node Families
Use Nodes when you know the kind of processor you need. Node families group related tools so you can compare options quickly instead of searching one long list.
| Family | Use it for |
|---|---|
| Terrain | Large terrain primitives and landform starters. |
| Primitive | Foundational shapes, gradients, patterns, and noise sources. |
| Simulate | Natural processes such as erosion, snow, water, vegetation, and deposition. |
| Surface | Surface breakup, stratification, rocks, sand, terraces, and texture-like terrain detail. |
| Modify | Filtering, remapping, warping, shaping, and cleanup operations. |
| Derive | Masks and data maps derived from terrain, color, flow, slope, or surface structure. |
| Colorize | Terrain color, palettes, channel operations, and color processing. |
| Utility | Graph organization, control flow, routing, masking, and helper logic. |
| Output | Rendering, baking, export, and downstream handoff nodes. |
Integration Reference
Use Gaea2Houdini when you need reference material for Gaea nodes exposed through the Houdini bridge.
Suggested Paths
If you know the node name, use search or jump directly through the sidebar.
If you only know the job, start with the family table above, then compare the pages inside that family.
If a node page feels too brief, check whether it has an official video block or a draft visual/example note. Those notes mark the next places where screenshots, comparisons, or workflow examples should be added.
