Boca de incêndio (alto poli) Modelo 3D

(sorry for bad English) This hydrant model made in Autodesk Maya 2016 Extension 2. The Maya Binary file and FBX file included all objects in groups, but the FBX doesn't includes the mia materials, just the model and simple lambert materials, because the maya didn't export tha mia material except in maya binary. I attached the normal map that I used. Not UV mapped so professional. The render picture made with physical sky and some light, the product doesn't include it. I'm a beginner so I would be glad if you support me with the purchase, to make better and better products.
