SceneTidy provides a set of tools to streamline and organize Blender projects. It automates the removal of unused data, including orphan materials, textures, and meshes, to assist with memory management. The addon includes utilities to quickly detect and delete duplicate objects within a scene to reduce outliner clutter. Additionally, it offers mesh optimization functions such as merging overlapping vertices and recalculating normals to ensure geometry is prepared for export or further modification.
