Some patterns are discontinuous, meaning their slope is infinite. These patterns are not suitable for use as object normals. These patterns work best with textures and media:
crackle patterns are mixed cases in that they are discontinuous at their respective boundaries. However, there is no limit to the different number of values, in the range of 0 to 1, that they can generate. When using the
solid keyword with the
crackle pattern it becomes discontinuous. The
tiling patterns are also discontinuous at their respective boundaries, while other portions ramp.
