This model was based on photogrammetry that provided the high poly model in addition to the textures.

then a low poly model for each section was modeled using the dimensions and the proportions of the high poly models.

Low poly models had to be unwrapped in order to do a projection out of the photogrammetry models.

The textures was than refined and fixed using photoshop than applied in the scene.

I used vray for the renderings, and 3Ds max for modeling.
