By default, asset nodes are translucent so you can partially see external nodes or connections underneath them. You can make asset nodes opaque by selecting Opaque Assets from the Hypergraph or Hypershade options menu.
You can also set the background for each asset in the Hypergraph to a custom image. This can help you quickly identify an asset by sight.
To customize the background of an asset in the Hypergraph
-click
the border of your asset and select Set Background Image from
the pop-up menu.
