Projection Spherical


The Spherical projection is used for Environment textures and IESAn IES light is the lighting information representing the real-world lighting values for specific light fixtures. For more information, visit Light distributions. It performs latitude-longitude mapping for the UV coordinates, and for Procedural textures, the W coordinate is the distance from the origin.
