Fire hydrant, the model was created with reference to real photos, a mix of several photos to achieve this result.
The 3d model contains a small amount of polygons, but you can apply the subdivision of mesh to the 3D model and still the texture will not distort.
The textures were made painted in Substance Painter, but in the project you will find the textures in 4k.
