UAnimInstance::Blueprint_GetSlotMontageLocalWeight
#include "Animation/AnimInstance.h"
Access: public
Specifiers: UFUNCTIONBlueprintPure
Description
Returns the current local blend weight (0–1) of any montage playing in the named slot. Returns 0 if no montage is active in that slot.
Caveats & Gotchas
- • The function is named with the Blueprint_ prefix for historical reasons — C++ callers should use the same name; there is no separate non-Blueprint variant.
- • This function is BlueprintThreadSafe and evaluates on the animation worker thread, but the returned weight reflects the value computed in the previous frame — not the value being evaluated in the current graph update.
