Gervasoni InOut 41, 42 and 43 ceramic ottoman / coffee table, designed by Paola Navone. This model is unwrapped, hand painted textures exist for all 3 colors (blue, white and anthracite) in all 3 sizes. This products color and finishing varies in real life, you can overlay these texture variations for an even 'rougher' look.
The vray version uses procedural noise displacement, but that's only needed for close-ups. Enable the displacement maps in vray materials if you want to achieve the exact same look as in the previews. Materials for other engines are setup as simple diffuse and bump.
