UKismetMathLibrary::NotEqual_LinearColorLinearColor

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns true if A and B differ on any channel (A != B). This is the Blueprint != operator for LinearColor.

Caveats & Gotchas

• Like EqualEqual_LinearColorLinearColor, this uses exact floating-point comparison — two colors that should be "the same" after arithmetic operations may still return true here due to floating-point error.
• Checking inequality before branching on a color is a code smell in most gameplay contexts; prefer a tolerance-based check with LinearColor_IsNearEqual.

Example

Dirty-check before applying a material update C++

if (UKismetMathLibrary::NotEqual_LinearColorLinearColor(CachedColor, NewColor))
{
    CachedColor = NewColor;
    DynamicMaterial->SetVectorParameterValue(TEXT("Tint"), NewColor);
}
