For the Ray Cube type, the reflection is not physically accurate with regard to the reflecting surface; i.e., the image reflected on a sphere will not show any distortion from the curvature of the sphere. This is mainly important when using a TIFF Image background.</p>

For the Two Planes background type, reflections are physically accurate, and show proper distortion based on the reflecting surface. The Mapping Mode option at the bottom of the dialog is enabled only for this background type, and allows you to specify how the backgrounds are stretched to accommodate this more realistic reflection.</p>
