Sculpture - Bronze Links Object - Pottery Barn (PBR metallic\roughness)

The object has small dimensions (HxWxD): 150 x 270 x 250 mm

Keep in mind that the model is PBR, but the material is set up in V-Ray Next, earlier versions of V-Ray do not support metallic maps, so you will need to convert the maps to a specular/glossiness workflow. In Corona Render, support for metallic cards seems to be only from the 7th version.
