This is a Disco ball.

- All the mirror tiles are the same size and well oriented.

- UVs are unwrapped.

- The file is made in order for you to have access to the way the ball was created: There is a version with the modifiers not applied and the construction elements were not deleted (see layers).

- The file is easy to use: everything is named properly (geometry, dataBlocks, Materials, Layers, etc...).
