Reference:Dents Pattern

The dents pattern was originally designed only to be used as a normal pattern. It is especially interesting when used with metallic textures. It gives impressions into the metal surface that look like dents have been beaten into the surface with a hammer. Usually the dents 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 dents pattern is similar to normal dents but is not identical as are most normals when compared to pigments.
