Although this thing can do so much more, I bought it mainly for the Deconstruct BP product that’s included in this. Deconstruct can split Blueprints into its components, which is super useful if you want to rebuild something that only exists as a blueprint. Also, some blueprints are made from actor components rather than harvested things, which makes it tricky to reference them in code.
The effector itself is something EPIC have been building into a fully fledged motion design feature inside UE, so it might become obsolete at some point when it’s superseded by the plugin. For now it’s a great way to animate objects by dragging an effector past them.
