|
infoBits (ib)
|
32-bit unsigned integer
|
Passes information from one node that may be needed by another node.
Using this field, a file texture node with advanced filtering turned on (such as Quadratic filtering) can be used simultaneously
as both a color map and a bump map. When rendering, Maya computes the color map using advanced filtering, but computes the
bump map without it since advanced filtering is incompatible with bump mapping.
