Installation

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

Usage

1. Open the Gift Box tab in the 3D viewport sidebar (N), or use Add (Shift+A), Gift Boxes.
2. Click a design picture and pick an unboxing celebration (or Still Gift), then press Add Gift. It appears at the 3D cursor.
3. With the gift selected, change it in the sidebar: box style, shape and size, wrapping paper, ribbon and bow, gift tag. The gift rebuilds live.
4. In the Unboxing Celebration box type your message, pick the confetti colors and press Play to watch the unboxing. Opening & Timing sets when and how fast it opens.
5. Surprise Me gives a random gift (Shift+click: a random celebration too); Vary changes only the small random details; Reset goes back to the picked design.
6. Make Plain Mesh (Mesh section) keeps the gift as a normal mesh with its animation.
