Beautiful Backlights is an addon for Blender that focuses on quickly decorating scenes. Developed by studioromanrec, it works under the Cycles render engine and is aimed at settings like night cities and nightclubs.
The addon supports Blender 4.0 and 3.6, and it's released under the GPL license. It was published almost three years ago and ships with documentation. A demo video is also available if you want a look at the addon before installing.
Beautiful Backlights is also featured in the Studioromanrec Blender Add-Ons Bundle, a collection of 33 products, alongside other tools from the same creator. If you build scenes in Cycles and want a straightforward way to decorate them, this addon offers a focused option within the superhive library.
