HEGoNode3D

Overview

HEGoNode3D is the default node you will use to bring an HDA into Godot. This page focuses on HEGoNode3D data exchange, split into Inputs and Outputs.

HEGoNode3D supports:

• Feeding Path3D, MeshInstance3D, CSGShape3D, and Terrain3D into Houdini

• Generating bespoke geo as MeshInstance3D nodes, including LODs and material assignment

• Instancing meshes via MultiMeshInstance3D nodes

• Generating Terrain3D terrains from heightfields

• Spawning Terrain3D instancer content from points

• Spawning nodes by class name and setting most properties

• Spawning scenes by resource path

Usage

Create a HEGoNode3D in your scene, open the HEGo bottom panel, assign an HDA, then recook. Inputs are converted to Houdini data before cook, and outputs are regenerated after cook based on attributes described below.

Inputs

The following sections describe what HEGoNode3D sends into Houdini when you connect different Godot node types as HDA inputs.

Supported input types include Path3D, MeshInstance3D, CSGShape3D, and Terrain3D.

• Inputs
  • Path3D Input
  • MeshInstance3D and CSGShape3D Inputs
  • Terrain3D Input

Outputs

The following sections describe output-side attributes read after cook. Choose the output type that best fits your use case: geometry, instancing, object spawning, or Terrain3D.

• Outputs
  • Geometry Output
  • Instancing Output
  • Object Spawning Output
  • Terrain3D Output

Parameters

The following sections describe how HDA parameter UI is generated in the HEGo bottom panel, which parameter families are supported, and known limitations.
