Randomize ID--
The 'Randomize ID' channel modifier generates randomized ID values for creating predictable quasi-random particle effects based on fixed IDs.
Input: Represents what would be the input value that would be randomized.
Key: The Key channel is used to initialize the random number generator. A change in the Key value results in a changing random value.
Minimum Value: Defines the minimum value generated by the random number generator.
Maximum Value: Defines the maximum value generated by the random number generator.
Scale: The 'Scale' option is a multiplier value that scales the resulting randomly generated value.
