A Node is a set of logic that can either stand on its own, or be attached to an object. 

Objects from the asset library already have a Visual Node, which controls the visual properties of the object including it's 3D model & visual materials. Some objects may also have a Physical Node that define physical properties.

Each Node has editable parameters that can be accessed via the Advanced Details panel when an object is selected.

You can:

• Add new Nodes to an object from the ➕ button, and remove them via the 🗑️ button.
• Add new Nodes independent from any objects via the Logic Menu found in the Toolbar.
