UKismetAnimationLibrary::K2_MakePerlinNoiseAndRemap
#include "KismetAnimationLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Samples 1D Perlin noise at Value and remaps the result into the given output range. The single-float counterpart to K2_MakePerlinNoiseVectorAndRemap, useful for a single smooth scalar like a breathing curve.
Caveats & Gotchas
- • Raw noise output is roughly in [-1, 1]; the default RangeOutMin/Max values pass it through unchanged.
- • Drive Value with a continuously increasing input (e.g. time * frequency) to get smooth animated motion — a static Value returns a static result every call.

float Example
Smooth breathing scale driven by time C++
const float Time = GetWorld()->GetTimeSeconds();
const float BreathScale = UKismetAnimationLibrary::K2_MakePerlinNoiseAndRemap(Time * 0.5f, 0.95f, 1.05f);Tags
