Visualizing the photon mapping can aid in determining whether the coverage
and density of photons for the scene is appropriate for the resulting final
image.
By default, the mental ray for Maya renderer rebuilds the photon map each
time you render a scene using Global Illumination. If you are rendering a
scene containing camera animation in which the objects and lights remain
static, or rendering several iterations of a single image, you may consider
turning off the Rebuild Photon Map setting in order to reduce the rendering
times for each frame.
