A well-known boombox is a budget model.PBR material with maps of resolution 4096 - ao, albedo (color), roughness, metalness, normal(baking with smooth groups, uvw island cutting by smooth groups), opacity and 1 tile texture for bump belt(1024)In preview not used metalness and ao maps(left in demand),and I think it is not difficult if necessary to replace some maps - the parameters for optimization. Also in the scene there is an hdri map for reflections(not in archive).*tris geometryDimensions:666x263x266 mm (l/h/d)
