UBlendSpace::TargetWeightInterpolationSpeedPerSec

property Engine Since 4.0

#include "Animation/BlendSpace.h"

Access: public Specifiers: UPROPERTYEditAnywhere

Description

Speed at which individual sample weights are allowed to change per second, letting the blend space jump directly between extremes instead of smoothly passing through intermediate positions.

Caveats & Gotchas

• A value of 0 (the default) disables this smoothing entirely — samples snap to their target weight immediately.
• This smooths per-sample weight, not the blend input position itself; it's a separate concept from the InterpolationParam axis smoothing used by FilterInput.

Signature

UPROPERTY(EditAnywhere, Category = SampleSmoothing, meta = (DisplayName = "Weight Speed", ClampMin = "0")) float TargetWeightInterpolationSpeedPerSec = 0.0f;

Example

Enable weight speed limiting C++

// Typically set in the editor, but can be adjusted at runtime on a per-instance blend space asset:
MyBlendSpace->TargetWeightInterpolationSpeedPerSec = 2.0f; // half a second to fully switch samples
