Fractal textures are very useful for simulating many
natural phenomena. Some examples:
- Used as a bump map, Fractals can create surface textures like
sand or dirt.
- A stretched-out fractal bump map can make a metal surface look
brushed.
- Used as a color (and bump), Fractals can create patterns of
rust.
- Attached to the Cloud Texture imput of an Env Sky node,
Fractals create natural-looking clouds.
- Attached to the V Offset attribute of a 2d Texture Placement
node, Fractals produce a smearing effect, like a smear map.
- Attached to the Intensity attribute of a light, Fractals
produce a irregular lighting effect, useful for things such as
moonlight, or light passing through clouds.
You can create even more interesting effects by having one fractal
node attached to the Amplitude attribute of another. Aside from the
attributes listed here, Fractal inherits many other attributes from
its parent node, Texture2d. In the
table below, important attributes are shown in bold in the
description column.
