Type Alias MaterialOverrides

    | readonly (BaseMaterial3D | undefined)[]
    | ((material: BaseMaterial3D) => BaseMaterial3D)

The materials a Model3D draws instead of its source's

A record, by material label: every source material with that label is replaced. The glTF loader labels materials with their names in the file.
An array, by index into Scene3DSource#materials; an empty entry keeps the source's.
A function, called once for each source material, returning the material to draw instead.

Example

new Model3D({ source, materials: { Paint: redPaint } });
new Model3D({ source, materials: (material) => material.clone({ extraBits: [dissolveBit] }) });
