RandomStream Functions
In order to make use of a RandomStream variable, there are a set of functions which take a RandomStream as input and output a random value of different types, depending on the function.
Function

Description

Random Bool from Stream

Outputs either 0 or 1 at random.

Random Float from Stream

Outputs a random Float value in the range (0.0, 1.0).

Random Float in Range from Stream

Outputs a random Float value in the range (Min, Max).

Random Integer From Stream

Outputs a uniformly distributed random Integer value in the range (0, Max  1).

Random Integer In Range From Stream

Outputs a random Integer value in the range (Min, Max).

Random Rotator From Stream

Outputs a random Rotator value.

Random Unit Vector From Stream

Outputs a random unitlength Vector value.

Choosing one of the functions shown above will place it in the graph wired to the RandomStream variable.
An example of using RandomStream functions to randomly place and rotate a component belonging to the Blueprint is shown below:

As you can see, random Booleans, Floats, Integers, Vectors, and Rotators can all be pulled from the same stream.
