The ground plane provides an infinite horizontal platform for the image that stretches to the horizon in all directions positioned at a defined elevation. The ground plane renders much faster than using a large planar surface as a base.
Turns the ground plane on. Ground plane disabled (left) and enabled (right).
Applies a transparent alpha channel to the ground plane so the image can be composited with the cast shadow into another image. See: Wikipedia article: Alpha compositing. Ground plane shows shadow, but is otherwise transparent in the image.
Specifies the ground plane’s height above zero. Ground plane elevation above zero.
Assigns a material to the ground plane. Ground plane with raised elevation and water material.
