When you want a montage to play on all linked layers, you can enable the Use Main Instance Montage Evaluation Data property, which will use the main instance's montage data on all linked instances. For example, playing a montage on a main instance will play it on the linked layer too. This can be helpful for ensuring that montages are played in full, and not overridden by animation layers. For more information about using Linked Animation Blueprint Layers, see the Using Layered Animations for an example of how Montages can be used with layered animation systems.
