This wallpaper pack is free and made in Blender with Octane Render. I also made a tutorial that helps you create your own one.

If you love it, don't forget to give it some stars. If you have any feedback, just let me know.
Thanks and enjoy!
You'll get a zip file containing the wallpaper files and its resources (if any).
