Tripo Smart UV replaces messy or missing UVs with a clean, organized layout that is easy to paint, edit and retexture. Texture baking (on by default) transfers the existing materials onto the new layout, and a rigged model keeps its skeleton. Turn baking off to get the geometry with fresh UVs only, ready for a new texturing pass. Every result includes a UV atlas preview image. Accepts GLB and FBX, including quad meshes, up to 80,000 triangles: run Tripo Retopology first on denser models.
