UAnimInstance::SetUseMainInstanceMontageEvaluationData

function Engine Blueprint Since 5.0

#include "Animation/AnimInstance.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Controls whether a linked anim instance uses montage evaluation data from the main anim instance instead of its own. Set this when a sub-graph needs to mirror the main instance's montage blending.

Caveats & Gotchas

• Changing this at runtime mid-montage can cause a one-frame pop in blend weights because the instance switches data sources immediately.
• Has no effect on the main UAnimInstance — it only changes behaviour for instances running inside a Linked Anim Graph node.

Signature
