UAnimInstance::PlaySlotAnimationAsDynamicMontage_WithBlendSettings

function Engine Blueprint Since 5.3

#include "Animation/AnimInstance.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Variant of PlaySlotAnimationAsDynamicMontage that uses FMontageBlendSettings for both blend phases, providing the most complete control including sync-group-aware blending.

Caveats & Gotchas

• FMontageBlendSettings supersedes FAlphaBlendArgs as of UE 5.3 and supports additional blend modes including sync-group-based blending; prefer this over the WithBlendArgs variant for new code.
• Passing mismatched BlendProfile assets in BlendInSettings and BlendOutSettings may produce inconsistent per-bone weighting.
