- Updated the depth plane node group to load from an asset and simplified the interface. - Created a new build script for depth plane geometry nodes. - Introduced material layer groups for image and depth materials with appropriate sockets. - Added functionality to connect balloon normal scale to the image material. - Enhanced tests to validate the new node groups and their connections. - Ensured that production code does not create node groups directly.
