Export Formats
Hesiod has one export node per output kind. Pick the node whose input data
type matches what your graph produces (see
Heightmaps & Virtual Arrays for the data model:
VirtualArray is scalar/height, VirtualTexture is RGBA colour — they are not
interchangeable).
| Node | Writes | Format(s) | Input port → type |
|---|---|---|---|
ExportHeightmap |
Grayscale heightmap | PNG 16-bit, PNG 8-bit, RAW 16-bit (Unity) | input → VirtualArray |
ExportTexture |
Colour image | PNG (8- or 16-bit) | texture → VirtualTexture |
ExportNormalMap |
Normal map of a heightmap | PNG (8- or 16-bit) | input → VirtualArray |
ExportAsset |
3D mesh (+ optional texture/normal) | OBJ, FBX, GLB/GLTF, PLY, STL, COLLADA, 3DS, 3MF, X3D, STEP, Assimp | elevation, mask → VirtualArray; texture, normal map details → VirtualTexture |
ExportTiled |
Heightmap split into tiles | Per-tile images (selectable bit depth) | input → VirtualArray |
ExportCloud |
Point cloud | CSV | input → Cloud |
ExportCloudToPly |
Point cloud | PLY | cloud → Cloud (+ point_data1..3 → vector\<float>) |
ExportPointsToPly |
Point cloud | PLY | x/y/z + point_data1..3 → vector\<float> |
ExportPath |
Path / polyline | CSV | input → Path |
Importing
Two nodes read external files back into a graph:
| Node | Reads | Output port → type |
|---|---|---|
ImportHeightmap |
Grayscale PNG (8-bit) | output → VirtualArray |
ImportTexture |
Image file | texture → VirtualTexture |
Notes
- Heightmap vs texture:
ColorizeGradient/ColorizeSolidconvert a VirtualArray to a VirtualTexture, so a colourised result must go toExportTexture, notExportHeightmap. See Texturing & Colorize. auto_export: every export node has anauto_exporttoggle and anfnameparameter; withauto_exporton, the node writes whenever it recomputes.- Whole-graph export: to flatten and export a graph from the command line, see Batch / Headless Mode. For the in-app bake workflow, see Bake & Export.
