UV Noise VEX node
Disturbes the incoming parametric s and t coordinates using anti aliased noise gene…
This operator disturbs the incoming parametric s and t coordinates using anti aliased noise generated from the Surface Position (P) input.
The resulting s and t coordinates can be used as inputs to almost all of the pattern generators, such as Rings, Boxes, and Stripes.
Optionally, the noise amplitude can be clamped to a specified range. The clamping is done smoothly using a cubic interpolator. If a rolloff is specified, the inflection point of the blend will be shifted. If the rolloff is greater than 1, the shift will be to the right. If the rolloff is less than 1 (and greater than 0), the shift will be to the left.
For a denser noise, enable “Compute Absolute Noise Value”. The absolute value is computed before any clamping takes place.
If the P, s, and t inputs are not connected, the global variables by the same names will be used instead. Typically, you will use Rest Position or UV Space Change as P inputs. Valid sources for s and t include Shading Layer Parameter and UV Project.
