Assets > Advanced Assets

Creates an asset with no associated transform. As a result, this asset does not appear in the DAG hierarchy and you cannot transform it in the scene. You can parent nodes external to the asset to it, but you must use parent anchors or child anchors to do so.

Include Shaders: Automatically includes any shading nodes that the currently selected nodes are connected to into the asset.
Include Hierarchy: Automatically includes the specified nodes, relative to the selected nodes, into the asset. You can include related shape nodes, hierarchy below, hierarchy above, or all of the above.
