How do I convert an FBX file to MTL?

Upload your FBX file, choose MTL as the output format, and click Convert. The converter scans every material node in the FBX scene and writes a corresponding .mtl file with Kd, Ks, Ns, d, and map_Kd entries. Download the MTL and place it in the same folder as your OBJ to preserve material assignments.

Why would I convert FBX to MTL instead of keeping the FBX?

MTL is a plain-text material definition format widely supported by OBJ-based 3D applications, game engines, and renderers. Converting FBX to MTL lets you reuse materials without carrying over FBX's heavy scene hierarchy, animation curves, or skeletal rigs — which is useful when you only need surface properties and texture references.

Does the FBX to MTL conversion preserve all material properties?

It preserves diffuse color, specular color, shininess, opacity, and texture map references, including UV mapping and transparency. However, FBX-specific PBR extensions (roughness, metallic, normal maps via PBR nodes) and animated texture transforms are not part of the classic MTL specification, so those attributes are omitted unless they are baked into the texture maps.
