Value noise node¶
The Value noise node outputs a texture generated as a sum of Value noise functions with increasing frequencies and decreasing amplitudes. Value noise has a wide range of applications, such as stains, wood, dust…
The Value noise node does not accept any input.
The Value noise node provides a greyscale Value noise texture.
The Value noise node accepts the following parameters:
Scale X and Scale Y are the subdivisions of the first iteration
Iterations is the number of iterations
Persistance is the ratio between the amplitude of subsequent iterations. Lower values of persistance generate smoother textures.
The Color Value node generates an RGB image made of 3 greyscale Value Noise images.
The Value Warp1 and Value Warp2 nodes generate Value noise with domain warping.
