B1AnimNotifyState_DisableLayeredBlend

File: BlueClient2/Source/BlueClient/Animation/AnimNotifies/B1AnimNotifyState_DisableLayeredBlend.h / .cpp Base Class: UAnimNotifyState

Purpose

Temporarily disables one or more layered blend channels (slot layer, right arm, left arm) for the duration of the notify range. Used in animations where IK or additive layers should not interfere with the base pose (e.g., a full-body pickup animation that shouldn't blend with upper-body idle IK).

How to Add in the Editor

  1. Open an Animation Montage or Animation Sequence.
  2. Right-click on the Notify track → Add Notify State → B1AnimNotifyState_DisableLayeredBlend.
  3. Configure which blend channels to disable in the Details panel.

Editor Properties

Property Type Default Description
bDisableSlotLayer bool true Disables the entire slot layer (overrides the arm-specific options below)
bDisableRightArm bool false Disables only the right arm layer — only editable when bDisableSlotLayer is false
bDisableLeftArm bool false Disables only the left arm layer — only editable when bDisableSlotLayer is false

Behavior

Callback Action
NotifyBegin Builds EB1LayeredBlendTarget flags from checked properties, computes smoothing based on elapsed time since trigger, calls animInstance->SetLayeredBlendDisabled(target, true, bApplySmoothing)
NotifyEnd Calls animInstance->SetLayeredBlendDisabled(target, false) to re-enable all disabled channels
