Automatically animates a value over time, ping-ponging between start and end values.
Get Array Size
Returns the number of elements in the passed in Float Array object.
Get Object Transform
Returns transform values of the scene object.
Gradient
Returns the value of a linearly interpolated procedural gradient. The sample position is a 0-1 value given by the Ratio input.
HSV to RGB
Converts a color from HSV (Hue, Saturation, Value) to RGB (Red, Green, Blue).
Hue to RGB
Converts a hue value to an RGB (Red, Green, Blue) color.
LUT 3D
Converts the color using a lookup table texture.
Light Color
When used with a Loop (Lights) node, returns the color value of the current Light.
Light Direction
When used with a Loop (Lights) node, returns the world direction vector the current Light is facing.
Light Intensity
When used with a Loop (Lights) node, returns the intensity value of the current Light.
Light Position
When used with a Loop (Lights) node, returns the world position of the current Light.
Linear Tone Mapping
Applies a tone mapping curve that is mostly linear, but trails off in the shoulder region to avoid abrupt highlight clipping. It is applied automatically when PBR is used.
Linear to sRGB
Converts from linear colorspace to sRGB colorspace.
Loop ( 4x )
Creates a loop that executes multiple times and returns a single result.
Loop ( Dynamic )
Creates a dynamically sized loop that executes multiple times and returns a single result.
Loop ( Lights )
Creates a loop that executes once for each Light affecting the object and returns a single result.
Loop ( Triplanar UV )
Projects a texture from three different axes and blends the samples based on the surface normal. This method doesn't rely on UVs so it can be applied to any mesh. This node is used in conjunction with the Triplanar UV Coord node.
Loop Count
When used with a Loop node, returns the total iteration count for the matching Loop.
Loop Iteration
When used with a Loop node, returns the current iteration number for the matching loop.
Loop Ratio
When used with a Loop node, returns the ratio of the current iteration compared to total iterations.
Luminance
Outputs the luminance (grayscale) value of the color.
Matrix Export
Exports a matrix to outside of the sub-graph.
Matrix Import
Imports a matrix into the sub-graph.
Matrix Transpose
Returns the transpose of the input matrix.
Mixer
Highly configurable node that can mix many types of input and output.
Noise ( Simplex )
Generates a random value using simplex noise.
Offset Coords
Applies a horizontal and vertical offset to coordinates.
Override
Overrides the surface information of all nodes connected through its Input port.
Parallax Coords
Offsets coordinates based on the viewing angle to simulate the texture being at a certain depth. Can be used with Loop node to sample parallax at multiple depths, and simulate effects like ice cracks or shell based fur.
Pixelize Coords
Rounds coordinates into chunks, creating a pixelization effect.
Posterize
Rounds the input value into several possible results, creating a posterization effect.
Preview
Displays the preview of the graph output up to this node.

Sample Float Array
Samples a Float Array Object at a specific index and returns the value.
Saturation
Adjusts saturation on the color.
Scale Coords
Scales coordinates around a center point.
Scatter Coords
Moves the coordinates by a random amount, creating a scatter effect.
Scroll Coords
Scrolls coordinates over time.
Sepia
Applies a sepia tone to the color.
Shadow Sample
For Mesh Visuals with the Shadow Receiver option, samples the shadow color being received at this pixel. The default value is white (1,1,1), which means no shadow is being received.
Split Matrix
Splits a matrix into its individual columns or rows.
Split Vector
Splits a single input value into multiple configurable output values.
Sticky Note
A sticky note node that lets you write multiline comments and descriptions anywhere in the graph. This node can be resized to any dimension. It is similar to the Comment box, but the text goes inside the node area instead of on top.
