Random

Allows you to apply a random number generator to the MASH network.

Random Node

Enable X, Enable Y, Enable Z: Determines which axes get randomized.
Uniform Random: Applies the random X value to Y and Z as well.
Minimum Number, Maximum Number: The lowest and highest number that the node can output.
Random Seed: Sets the randomization for the generator.

Strength: Fades the node's effect for all the objects at the same time.
Random Strength: Smoothly fades the node's effect on all the objects in a random order.
Step Strength: Turns the node's effect off one object at a time.
Strength Map: Determines the input file (2D texture, animated texture, etc) that controls the node's effect.
Map Projection Axis: Determines the axis along which the Strength Map is projected.
Map Helper: Displays the object being used to interactively place the Strength Map in the scene. You can right-click the field to create a new helper object (a plane) if none exists. You can also middle-drag a mesh into this field or right-click to connect a selected mesh. If a mesh is already connected, you can also right-click to break its connection or show it in the Outliner.
Note: For the best results, assign the same texture to both the Strength Map and the Map Helper (this automatically happens when creating a new helper object).

Whole Numbers: Forces output values to be whole numbers.
Normalise Random: Normalizes all random numbers so that they fall within the 0-1 range in world units. Note that you can increase Strength to a value greater than 1.0 to offset this.

Allows you to customize the minimum and maximum values output on a per axis basis. The node only uses them when their value is not 0.
