Assets are objects that you can add to a scene, including characters, devices, elements, shaders, .fbx files, and so on.
Assets are listed in the Asset browser in a hierarchical tree structure. You can add them to the scene by dragging them from the Asset browser folders. You can also create favorite paths in the Asset browser to make shortcuts to your own .fbx files.
