Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the luggage_generator zip.

Usage

1. Open the Luggage tab in the 3D viewport sidebar (N) and click Add Luggage, or use Shift+A, Mesh, Luggage. The case appears at the 3D cursor.
2. Click the picture to pick another design. Surprise makes a random design, Vary changes the current one a little and Colors picks a new finish.
3. Open & Pose opens the lid, extends the handle, lifts the carry handles and turns the wheels. Keyframe these to animate.
4. Size & Shape, Shell Pattern and the feature panels (closure, wheels, handle, carry handles, trim, soft side, vintage, protective, duffel, interior) hold every setting. Materials & Condition sets the finish, colors, wear and dirt.
5. Convert to Mesh keeps the case as plain meshes for export; Delete removes it with all its parts.
