Angular Mapping
Controls the spherical/angular interpretation of the source image.
Spherical environment mapping
Converts an image into spherical texture mapping with angular mapping, texture depth, XYZ rotation and separate OpenGL/software filtering controls.
SphereMap prepares flat imagery for spherical use in reflections, refractions, environments or technical 3D projections. It is especially useful when a source is already intended to wrap around a sphere instead of a six-face cube.
Overview
SphereMap prepares flat imagery for spherical use in reflections, refractions, environments or technical 3D projections. It is especially useful when a source is already intended to wrap around a sphere instead of a six-face cube.
Think of SphereMap as a translator between a flat image and a sphere around the scene. Angular Mapping defines how the image wraps, while rotation determines which part of the map faces the camera.

Inspector
Start with these controls before reaching for more complicated workarounds.
Controls the spherical/angular interpretation of the source image.
Sets texture precision for the mapped result.
Chooses the order in which the sphere-map transform is evaluated.
Sets the X, Y and Z components of the control.
Sets the processing quality for this operation.
Use a lighter setting while building the comp if needed, then verify the final-quality result before render.

Provides a technical material identifier where relevant.
Practical setup
Prepare the environment image in the correct projection.
Enable the intended Angular Mapping mode.
Rotate the map rather than moving scene objects to compensate for orientation.
Choose filtering based on preview versus final render requirements.
Check the result around poles and seams.
Examples
Use a panorama as the surrounding reflection source for a 3D object.
Rotate the sphere map until its key light direction matches the scene.
