vArrayMapRange

Remap every value in a point array from one numeric range to another — the essential normalisation and scaling step between generators and renderers.

vArrayMapRange applies a range-mapping operation to every value in an upstream vArray, translating coordinates or numeric data from one input range into a target output range. Place it between any generator or modifier and vArrayCameraProjection to normalise, invert, or rescale point positions before rendering.

Parameters​

ParameterTypeDefaultDescription
Mode SelectInteger1Selects the remapping mode applied to all values in the array. Each integer index corresponds to a different strategy (clamped linear, unclamped, normalised, etc.). Check the Fusion UI tooltip for the mode index labels for your fuse version.
Show InputCheckboxOffReveals the ArrayA input port, allowing an upstream point array to be connected for range remapping.
Array AArray—Primary point array input. Connect any upstream vArray generator or modifier here to apply range mapping to its values.
Read the full description

vArrayMapRange is a precision scaling node that applies Fusion-style range remapping to every value in a vArray point table. Where a generator like vArrayPointsOnGrid outputs coordinates in its own internal units, MapRange lets you translate those values into whatever numeric range a downstream node expects — without expressions, Lua scripting, or modifier chains. The operation is applied per-value across the entire array in a single pass.

The Mode Select control switches between different remapping behaviours — for example, clamped linear mapping, unclamped extrapolation, or normalised 0–1 output. Because the extracted parameter type shows as Integer, it functions as a mode switcher rather than a continuous slider; each integer value selects a distinct mapping strategy. Check the UI tooltip in Fusion for the mode index labels, as these vary by fuse version.

In a typical pipeline, MapRange sits after a displacement or generator node and before vArrayCameraProjection. A common use case is normalising vArrayDisplaceValues output — the displacement can push coordinates outside the 0–1 normalised range, and MapRange clamps or remaps them back into a renderable space. It also works well after vArrayMath when arithmetic operations have shifted the value range beyond what ShapeRender expects.
