Import Highpoly
Import Highpoly loads high-resolution scanned or photogrammetry meshes to extract trunk profiles and reference geometry for procedural extension. The node is a wrapper for several scan and mesh utilities and has an interactive wizard state that guides through importing scanned geometry, assigning textures, and extracting trunk profiles. The extracted profiles feed into Graft Mesh.
For workflow context, see Scan Workflow and Trunk Extension.
Inputs
A high-resolution mesh: scan, sculpt, or other high-poly source. No SOP input required when the source is loaded via the wizard or the Source File parameter.
Outputs
The imported mesh with materials and profile selections, ready to feed Graft Mesh. Two output streams: the high-poly mesh and the selected profile points (carried separately downstream).
Modes / States
- Wizard. Python state. Press Enter (or the wizard button) to launch a guided import that walks through loading the mesh, assigning textures, selecting kept parts, and picking profile points.
- Advanced mode. Toggle to populate fields manually, as with any Houdini HDA.
Parameters

Process
| Parameter | Description |
|---|---|
| Trim Mesh | Sub-folder of trim-related controls. |
| Profiles to Extend | Sub-folder of profile-picker controls. |
Proxy Settings
| Parameter | Description |
|---|---|
| Proxy Reduction Mode | How the point-cloud preview is generated. |
| Point separation / percent | Density of the preview points. |
| Colour preview + correction | Colour controls on the preview. |

Internal utilities
- Import step. Reads the source mesh into the workflow.
- Scan Material. Assigns the material to the scan. Has its own dive target for COPs-based material editing.
- Scan to Parts. Lets the artist select, from the point cloud, which parts of the scan to keep.
- Scan Profiles. Interactive picker for the end-tube points used for procedural extension.

Grow Draw
Draw growth by hand. Author parts of a tree directly (a hero branch, a sketched silhouette) and have the simulator pick up from your input and fill in the rest procedurally.
Identify Shared Instances
Tags input geometry with a name attribute that identifies which pieces are shared instances. Used to preserve instance relationships through downstream Natsura processing and export.
