señal 3d para ar

Generate a 3D welcome sign for augmented reality with the text “Bienvenidos a la Biblioteca”. The sign should have a professional academic institutional style, elegant and modern, with highly readable raised letters. Use the representative colors of Universidad Colegio Mayor de Cundinamarca: dominant blue, ochre yellow accents, red details, and black or white for contrast. The sign should look clean, polished, formal, and suitable for a university library. Create it as a low poly, game-ready 3D object optimized for Unity AR, with simple materials, clean geometry, and good readability from medium distance. Add a subtle base or frame, but keep the design uncluttered. Export-ready style for FBX or OBJ.
