To remove an asset

1. Select the asset node you want to remove in the Hypergraph Connections editor.
2. Select Edit > Asset > Remove Asset.

The selected asset node is removed from the graph area of the Hypergraph and deleted from the file. The nodes within the deleted asset are either moved to the parent asset (if one exists), or to the top level of the dependency graph. Note that all connections (published or unpublished) to and from the internal nodes of the asset are retained.

To remove all the assets in your scene

1. Select Edit > Delete All by Type > Assets.

   All the assets in the scene are removed, but their contents remain in the scene.
