The transformation applied to the material property’s visual contents. Animatable.
Mac Catalyst 13.0+
SceneKit applies this transformation to the texture coordinates provided by the geometry object the material is attached to, then uses the resulting coordinates to map the material property’s contents across the surface of the material. (This transformation has no effect if the material property’s contents object is a constant color.)
For example, you can use this property to grow, offset, or rotate a texture relative to the surface of a material, as illustrated below.
