Inspector
Controls Tab
The Controls tab in the Inspector modifies the mapping of the image input to the sphere map.
Angular Mapping
Adjusts the texture coordinate mapping so the poles are less squashed and areas in the texture
get mapped to equal areas on the sphere. It turns the mapping of the latitude lines from a
hemispherical fisheye to an angular fisheye. This mapping attempts to preserve area and
makes it easier to paint on or modify a sphere map since the image is not as compressed at
the poles.
Rotation
Offers controls to rotate the texture map.
Material ID
This slider sets the numeric identifier assigned to this material. This value is rendered into the
MatID auxiliary channel if the corresponding option is enabled in the renderer.
The node expects an image with an aspect ratio of 2:1. Otherwise, the image is clamped
according to the following rules:
 2 * width > height: The width is fitted onto the sphere, and the poles display clamped
edges.
 2 * width < height: The height is fitted onto the sphere, and there is clamping about the
0-degree longitude line.
