This skybox is 18x15x5, fits any regular 512sqm parcel… and has only 11 prims!
A large window and a skylight provide lots of natural light.
The background image is semi-transparent, so it reflects the natural light of day and night.
You can use this skybox as your home, store, or tea house in the sky.
The building is one object; there’s no need to use a rezbox. You just rez the skybox and move it around as much as you want.
