Signal

Animates the points in your network using either 4D Perlin Noise or a Trigonometric function.

Signal Type

Determines the function driving the animation. Options include:

4D Noise: A gradient noise (Perlin) with an organic texture that can resemble marble, wood, clouds, fire, etc.
Looping Noise: A loopable version of 4D Noise.
Fractional Brownian Motion: Also known as Turbulence. Similar to 4D Noise except objects will speed up and slow down.
Trigonometry: A trigonometric function.

Transformation Space

Determines whether to transform points relative to their shared World space or their individual Local spaces.

Position

Position X, Position Y, Position Z: Specifies how much the signal affects the points' translations.

Rotation X, Rotation Y, Rotation Z: Specifies how much the signal affects the points' rotations.

Scale X, Scale Y, Scale Z: Specifies how much the signal affects the points' scales.
Uniform Scale: Scales points uniformly across all axes (uses the Scale X value only).
Positive Scale: Ensures points are only scaled to positive values.

Octaves: Sets the number of noise octaves. Higher values produce more detailed noise.
Persistence: The strength of each noise octave. Higher values make the noise more chaotic.
Loop Frames: Determines the number of frames until the noise loops. Only available when Signal Type is set to Looping Noise.

X Function, Y Function, Z Function: The type of trigonometric curve to use along each axis. Only applicable when the Signal Type is set to Trigonometry.

Enable Step: Offsets each point's noise/trig sample in time by the Step Amount multiplied by the point ID. Enable this to give each point a unique time offset. Disable it to generate more of a turbulence effect.
Step Amount: The multiplier to apply to each point ID when Step is enabled. Lower values cause all objects to have similar animation, while larger values will cause them to differ greatly.
Noise Scale: Scales the frequency of the noise or trig function.
Noise Scale Multiplier: Individually multiplies the Noise Scale's effect in the X, Y, and Z axes. Only available when Enable Step is turned on.
Time Scale: A multiplier for the current Time of the input object's animation sequence. Allows you to speed up, slow down, and even reverse animation.
Time: Displays the current frame.

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 shape of 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).

Transformation Space: Determines whether the node will transform objects according to their local or world space.
