receiveShadow :Boolean

Whether the material receives shadows.

renderable :Boolean

Whether it can be collected into the Render Queue.

Default Value: Vector3(1, 1, 1)

sh :SphericalHarmonics3

An instance of SphericalHarmonics3.

Type:

SphericalHarmonics3

shadowType :t3d.SHADOW_TYPE

Defines shadow map type. Note: In webgl1 or t3d.Scene#disableShadowSampler is true, soft shadow types will fallback to POISSON_SOFT without warning. Note: Point light only support POISSON_SOFT for now.

Type:

t3d.SHADOW_TYPE

Overrides: t3d.Light#shadowType
Default Value: SHADOW_TYPE.PCF3_SOFT

userData :Object

An object that can be used to store custom data about the t3d.Object3D. It should not hold references to functions as these will not be cloned.
