Clicking this exposes your Blueprint's variables in the Details panel, including default variables from the Blueprint class. Root Motion Mode: Controls how root motion is applied within this Animation Blueprint. You can select the following options: No Root Motion Extraction, which causes no root motion to be extracted or applied. Ignore Root Motion, which extracts root motion, but does not apply it. Root Motion from Everything, which enables root motion from all animation sources. Typically you should not enable this in multiplayer or network setups. Root Motion from Montages Only, which causes root motion to only apply from Animation Montages. This is a more suitable option for multiplayer or network setups. Receive Notifies from Linked Instances: Whether to process notifies from any linked anim instances. Propagate Notifies to Linked Instances: Whether to propagate notifies to any linked anim instances. Use Main Instance Montage Evaluation Data: Enabling this causes linked instances to use the main instances' montage data, synchronizing all instances when the main instance plays a montage.
