Material Nodes

Material Tag

Tags all triangles of a geometry with a material slot index. Wire a Material Parameter node into the slot input.

Inputs

• Geometry (Geometry)
• Material Slot (Float)
• Slot Override (Float)

Outputs

• Geometry (Geometry)

Tips

• Wire Slot Override (e.g. from a loop index or scatter spawn seed) to pick a different submesh bucket per instance: the basis for N-submesh texture variation.
• In a top-level graph: drive Slot Override with a Random Int for an even spread across buckets, or Weighted Pick for uneven frequencies. In a sub-graph: use a Material Palette parameter instead – Slot Override cannot be remapped during inlining.
• To paint a different texture on each piece, wire a Switch into Set Material Property downstream.

Set Material Property

Paints a texture or color onto one material slot, only on the geometry flowing through, so every piece can have its own look while sharing one material.

Inputs

• Geometry (Geometry)
• Material Slot (Float)
• Texture (Texture)
• Color (Color)

Outputs

• Geometry (Geometry)

Options

• _materialSlotIndex: Which Material Slot parameter receives the override. -1 means no slot selected.
• _propertyName: Shader property to override. Empty means Main Texture or Main Color depending on mode.
• _isColorMode: True when a Color-type property is selected; false for Texture-type.
• _colorValue: Inline RGBA color used when the Color port is unwired.

Limitations

• Bake is not supported: use Scene Instance to preview and apply material overrides.
• ChunkSystem (streaming worlds) cannot apply per-instance property blocks.

Tips

• Material Tag assigns a slot; this node paints it.
• Drive the texture from a Switch in a loop for per-piece variation.
• Each distinct texture or color is one extra draw call.
• Designers can swap textures and colors on the InfinioInstance without regenerating.
• For per-piece tint without extra draw calls, use Assign Vertex Color instead.
