Spanner with worn red paint. This can be used as a prop or even as a melee weapon.
Fully textured realtime asset with Metal-Roughness PBR textures (1024x1024 resolution .tga).
All tris. No isolated vertices or co-planar faces. Vertex normals were set properly in 3D max to avoid smoothing errors. Normal map was then baked in xNormal with Mikk T-space tangent basis.
Please note that to get most out of PBR textured asset it is necessary to use rendering engine that is capable of taking advantage of this scheme.
