The bumps
pattern was originally designed only to be used as a normal pattern. It uses a very smooth, random noise function that creates the look of rolling hills when scaled large or a bumpy orange peal when scaled small. Usually the bumps are about 1 unit apart.
When used as a normal pattern, this pattern uses a specialized normal perturbation function. This means that the pattern cannot be used with normal_map
, slope_map
or wave type modifiers in a normal
statement.
When used as a pigment pattern or texture pattern, the bumps
pattern is identical to bozo
or spotted
and is similar to normal bumps but is not identical as are most normals when compared to pigments.
