The Bump shader provides
bump mapping for the mental ray renderer. Bumps are created by perturbing
face normals before the object is rendered, using the same method
bump mapping for
the scanline renderer.
Although you can
assign a Bump shader to the Surface component, if you assign only
Bump shader, the surface will render as black. For the Surface component,
use the Bump shader in a
or for the
, use the Bump component itself.
Bump (3dsmax) Parameters
Adjust the bump effect by
multiplying the map values. Negative Multiplier values reverse the
bump effect: hollow areas now protrude, and raised areas become

a map to use for generating bumps. Bump mapping uses the intensity
of the map to affect the surface of the material. The intensity affects
the apparent bumpiness of the surface: white areas protrude, and
black areas recede.
The controls on this
rollout let you assign a map or shader to the Multiplier parameter.
