**Spherical** projection performs spherical, latitude-longitude mapping for the U and V coordinates. For procedural textures, the W coordinate is the distance from the origin. This mapping is used for **Environment** textures and **IESAn IES light is the lighting information representing the real-world lighting values for specific light fixtures.

**Transform** - The transformation applied to the projection. Accepts a **Transform** node.

**Coordinate Space** - The coordinate space used by the projection.
