    Properties

    thicknessFactor?: number

    The thickness of the volume beneath the surface. The value is given in the coordinate space of the mesh. If the value is 0 the material is thin-walled. Otherwise the material is a volume boundary. The doubleSided property has no effect on volume boundaries. Range is [0, +inf). Default to 0.

    thicknessTexture?: ITextureInfo

    A texture that defines the thickness, stored in the G channel. This will be multiplied by thicknessFactor. Range is [0, 1].

    attenuationDistance?: number

    Density of the medium given as the average distance that light travels in the medium before interacting with a particle. The value is given in world space. Range is (0, +inf). Default to Infinity.

    attenuationColor?: [number, number, number]

    The color that white light turns into due to absorption when reaching the attenuation distance. Default to [1, 1, 1].
