How do I convert GLTF to MTL with LetsConvert?

Upload your GLTF file, choose MTL as the output format, and click 'Convert'. The tool will extract material definitions and texture references from the GLTF file, generating a standard MTL document. You can download the MTL file along with any extracted texture maps in a bundle.

Why should I convert a GLTF file to MTL?

GLTF is a modern, compact 3D format optimized for web and real-time rendering, while MTL is a long-established material library format paired with OBJ files. Converting GLTF to MTL is useful when you need to reuse materials in applications that only support OBJ/MTL, such as older CAD tools, 3D printing software, or custom render pipelines. It also lets you strip away geometry and keep just the material data.

What materials and properties are preserved during GLTF to MTL conversion?

All material properties are mapped to MTL equivalents: diffuse and ambient colors, transparency (d), specular highlights (Ns, Ns), and emissive values. Texture maps used in GLTF, like base color, metallic/roughness, normal, and occlusion, are exported as separate image files, and the MTL file is updated with proper map_Kd, map_Bump, etc., references. UV coordinates remain associated with the vertex data, ensuring textures align correctly when the MTL is used with the original OBJ.
