Unity KnotNone

Unity's KnotNone is a setting used to control how objects are attached together in the Unity Editor. When set to KnotNone, it means no specific connection or joint is established between objects; they remain independent and unaffected by each other’s movements or physics. This is useful when you want objects to exist in the scene without influence from other objects’ transformations or physics behaviors, providing a default state where no spatial or physical relationship is enforced. In essence, KnotNone ensures complete independence between objects' positions and states until explicitly connected or scripted otherwise.
