Space Elements Addon works inside Blender to assemble space scenes. Starting is a matter of clicking the Setup Space button to create the lighting and background, then adding a planet of your choice, moving around it, and dropping in an asset. The addon handles the galaxy background setup and lighting setup for you, and includes automatic composition with bloom in Cycles.
The pack ships with five realistic planets, fully shaded, along with five assets covering satellites, a shuttle, and the ISS. These assets are free to redistribute and use anywhere for any purpose. Easy settings give you control over how each element behaves in your scene.
The addon lives on the N-Panel and is built to be straightforward to use. It renders with Cycles and Eevee, and documentation is provided. A demo video is also available for those who want to see it before diving in. Developed by EdenWeby 3D, it targets a broad range of Blender releases so a wide user base can pick it up.
