Function Graph Editor-- This is the deepest level of material edition. The function graph editor lets you build your own shaders by selecting from the multitude of preset noises, linking them to available parameters, and creating an infinite range of all new functions to apply on your material (or to generate procedural terrain altitudes)! Although a lot of effort has gone into making the creation of custom shaders easy and intuitive (thanks to the SmartGraph technology, inspired by artificial intelligence systems), the sheer power of the function graph editor can be initially overwhelming. Thanks to the new parametric mapping mode, you'll accurately fit textures onto objects! (Parametric mapping mode come in addition to world and object mappings).
