Smart Scene Optimizer is an add-on that automates scene clean-up and organization for rendering and game engine export. It provides tools to remove loose geometry, empty vertex groups, unused materials, and duplicate modifiers across all mesh objects in a file.

The toolset includes dedicated geometry, material, transform, and object clean-up operations. Users can merge close vertices with adjustable thresholds, delete empty or non-mesh objects, apply transforms globally, and auto-rename objects in the Outliner. Additionally, it offers a feature to combine meshes that share the same material, reducing draw calls for real-time applications and game development.
