Instancing Output

Use MultiMeshInstance3D output to efficiently render many instances of the same mesh with different transforms and colors. This is ideal for trees, rocks, and other repeated elements.

Point Attributes

Transform and color data is specified via point attributes:

Attribute Name	Attribute Type	Attribute Owner	Description
N	Vector	Point	Forward direction (positive Z)
Cd	Vector	Point	Per-instance color (enables MultiMesh colors)
up	Vector	Point	Up vector (Copy to Points style)
pscale	Float	Point	Uniform scale
scale	Vector	Point	Non-uniform scale, multiplied by pscale
hego_use_multimesh	Int	Point	Required. Set to 1 to enable MultiMesh output
hego_multimesh	String	Point	Target node path under HEGoNode3D/Outputs
hego_mesh_resource	String	Point	Mesh resource path to instance

Example

A point wrangle over scattered points, instancing a rock scene with random scale and orientation:

// Point wrangle on the scatter output
i@hego_use_multimesh = 1;                              // required
s@hego_multimesh = "Rocks";                            // node name under Outputs
s@hego_mesh_resource = "res://meshes/rock_01.res";     // the mesh to instance

f@pscale = fit01(rand(@ptnum), 0.6, 1.4);
v@up = {0, 1, 0};
v@N = normalize(set(rand(@ptnum + 11) - 0.5, 0, rand(@ptnum + 27) - 0.5));

Every attribute except hego_use_multimesh and hego_mesh_resource is optional: without N and up the instances keep the default orientation, without pscale or scale they stay at unit size, and Cd only needs to be there if you want per-instance colour.

Splitting into Multiple Instancers

You can split one output into multiple MultiMesh instancers by assigning different hego_multimesh paths across points. This allows you to create separate instancer groups with different meshes or configurations.
