UAnimInstance::GetSlotMontageLocalWeight

function Engine Since 4.14

#include "Animation/AnimInstance.h"

Access: public Specifiers: ENGINE_API

Description

Returns the local blend weight (0–1) of any montage active in the named slot, without factoring in parent blend node weights. This is the raw contribution of the montage at that specific slot node.

Caveats & Gotchas

• The local weight represents the slot's own blend state and does not account for how much the slot contributes to the final pose after upstream blending. For the final contribution, use GetSlotMontageGlobalWeight.
• Returns 0 when no montage is playing in the slot, including during the blend-out phase after Montage_Stop has been called but the montage has not yet finished fading.
