Cloud Fractal Shader v3
Node Descrption and Purpose: The Cloud Fractal Shader is a specialized form of the Power Fractal Shader v3 which provides the base shapes for a cloud layer. The default settings are customized to produce realistic cloud forms and scales, but it is otherwise identical to the Power Fractal Shader v3, so you can reference the documentation for that shaderA shader is a program or set of instructions used in 3D computer graphics to determine the final surface properties of an object or image. This can include arbitrarily complex descriptions of light absorption and diffusion, texture mapping, reflection and refraction, shadowing, surface displacement and post-processing effects. In Terragen 2 shaders are used to construct and modify almost every element of a scene. for additional information.
