This rather unusual looking shader comes directly from one of Ken Musgrave's chapters in " Texturing & Modeling A Procedural Approach" Second Edition. If you are interested in coding up your own procedural textures and materials this is the book to pick up. I hadn't seen anyone actually implement it for a commercial package so I gave it a try. The result is rather pleasing but rather slow and not too friendly for the parameters.
Size: Sets the scale of the function.
Arg 0-8: These nine parameters naturally control various aspects of the map. Unfortunately, as Ken Musgrave, the author of the function, explains their influence is not very straightforward. Moreover, the parameters are interrelated, which makes their effect even more difficult to quantify. Instead of trying to label these elusive controls I figure its best to leave them blank and let you, the user, play with them. Enjoy!
As mentioned above this procedural is brittle, meaning that it can easily be pushed into creating an unappealing mess. The parameters, save for the size control, are non-intuitive and often lead to less than stellar looking content. This leads to a really poor UI but, if you are willing to play with the controls some interesting results are possible.
Please do not redistribute these files. Changes/bug fixes may be made to the plugin and it makes it much easier to guarantee you have the latest version if it is grabbed it from this site. Thanks.
