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 peel 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
slope_map or wave type modifiers in a
When used as a pigment pattern or texture pattern, the
bumps pattern is identical to
spotted and is similar to normal bumps but is not identical as are most normals when compared to
Note: The appearance of the bumps pattern depends on the noise_generator used. The
default type is 2. This may be changed using the
noise_generator keyword (See section "Pattern
Modifiers / Noise_generator").
