SmartRetopo Ultimate is an add-on that consolidates retopology and game asset preparation tasks into a single sidebar panel. It utilizes Blender's native QuadriFlow remesher to automate retopology based on user-defined target face counts. The toolset includes a multi-level LOD generator that produces three levels of detail (LOD1, LOD2, LOD3) using preset decimation ratios for game engine implementation.

Additionally, the add-on features automated mesh cleanup operators to remove loose geometry, merge doubled vertices, and recalculate normals prior to processing. It also provides built-in tools for baking normal maps from high-poly sculpts to the generated low-poly meshes, and supports exporting game-ready FBX files with applied transforms and smooth shading.
