Make single-sided meshes double-sided without changing your shader. This tool provides a one-click solution to convert any single-sided mesh into a double-sided mesh by generating a new mesh with doubled and inverted vertices, triangles, UVs, and supporting sub-meshes and materials. The new mesh is stored as a separate asset next to the original, preserving the original structure. It supports skinned meshes and animations, including bone weights and poses, and works with multi-material meshes, allowing duplication of sub-meshes to assign new materials to the inverted side. The tool also supports multi-object editing, requiring no runtime components—just a new mesh asset. No custom shaders are needed. Full source code is included. Compatible with Unity 2019, 2020, 2021, 2022 and later versions. Note: While the tool supports UNDO, the created mesh assets remain after the operation. Baked vertex animations are not supported, though animations using bones or shaders are fully functional.
