Noise ShaderBasic Shader
Noise is a special type of channel shader that produces 32 types of noise. The shader can calculate the noise in 2D (Space set to UV 2D) or in 3D space. The advantage of 3D noise is that you don’t have to worry about mapping or seams in the texture.
Noise is an integral component of any render system because it turns an otherwise far too smooth surface into a more or less randomly uneven surface (e.g., when used in the Bump channel). Below are examples of all Noise types available in the Noise Shader. Their respective effects are shown using Sub Polygon Displacement.
On the left is the Noise Shader as a normal grayscale image; on the right is the same Noise Shader on a sphere, with different Noise scales (Global Scale). A similar effect can be achieved by using MoGraph’s Displace Deformer .
