The seed is a number that is used to initialize the random generator. A same seed setting will generate the same graphical result.
Seeds can be auto-incremented at each activation using the parameter Increment At Activation.
This parameter is used in a lot of elements such as every kind of noises (noise Noise FunctionDefine a procedural noise functionRead More, Noise layerGenerate a possibly animated noise imageRead More, TurbulenceApply a random motion to particlesRead More).
Increment At Activation (On/off option) : Enable this to change the seed every time the element is activated
