Spherical Projection


Spherical projections work with Environment textures and IESAn IES light is the lighting information representing the real-world lighting values for specific light fixtures.

For Procedural textures, the W coordinate is the distance from the origin.


Figure 1: Using Spherical projection to map a Texture to a sphere


When using an Image texture to light a scene with the Sun And Sky node, spherical mapping combined with a Transform node rotates and translates the Environment sphere's Texture.
