TIP To avoid busy moiré patterns in the grid, increase the value of Size.
Photon Renders the effect of a photon map in the screen. This requires that
a photon map be present (to render caustics or global illumination). If no
photon map is present, the Photon rendering looks just like the nondiagnostic
rendering of the scene: the mental ray renderer first renders the shaded scene,
then replaces it with the pseudocolor image.
■ Density Renders the photon map as it is projected into the scene. High
density is displayed in red, and lower values render in increasingly cooler
colors.
■ Irradiance Similar to the Density rendering, but shades the photons based
on their irradiance. The maximum irradiance is rendered in red, and lower
values render in increasingly cooler colors.
BSP Renders a visualization of the parameters used by the tree in the
BSP
ray-trace acceleration method
on page 6141 . If a message from the renderer
reports excessively large depth or size values, or if rendering seems unusually
slow, this can help you locate the problem.
■ Depth Shows the depth of the tree, with top faces in bright red, and
increasingly deep faces in increasingly cool colors.
■ Size Shows the size of leaves in the tree, with differently sized leaves
indicated by different colors.
Final Gather Renders the scene with pre-processing final-gather points
displayed as green dots, and tile-rendering (final render) final-gather points
displayed as red dots.
For animation purposes, the presence of red dots is undesirable. To resolve
this, use the
Interpolate Over Num. FG Points setting on page 6108 instead of
the
Radius Interpolation Method on page 6113 , or, if you prefer the latter, keep
the Min. Radius setting as close as possible to the Radius setting; that is, the
maximum radius.
