3D Valley

3D Valley is a free toolkit built around one fast workflow: turn a photo or a sentence into a textured 3D model in roughly a minute, then keep working on it. The generator accepts JPG, PNG, WebP or HEIC input for a single object, and text-to-3D does the same from a written description alone. Results download as GLB, OBJ or STL, ready for printing, a game engine or the web.

Beyond generation, the site is a full repair and preparation bench. Repair, Remesh, Reduce and Compress fix or slim down meshes you already have, Retexture swaps colours and materials while keeping the shape, and the texture generator produces seamless, tiling maps from a description or a photo. Most of these file tools execute in the browser, so your model never leaves your device; remeshing runs locally too except on phones or very large models.

There is also a substantial library: more than 10,000 CC0 models, seamless textures and HDRIs sourced from Kenney, KayKit, Quaternius, Poly Haven, ambientCG, the Smithsonian and others, searchable by meaning and free to use without attribution. For automation, 3D Valley publishes an MCP server for Claude, ChatGPT, Cursor and VS Code plus a REST API, letting an agent create models, retexture, remesh and search the library on the same credits as the site. Note that this domain previously hosted a 3D model and tutorial site from 2003; the domain changed hands in 2026 and the current service is an independent rebuild with no connection to the original content.
