Published by NORR11, Hippo is a sofa that becomes the centre of attention in a room and brings a touch of both elegance and simplicity to any interior. Interesting from every angle, the Hippo sofa shares the same characteristic leg as the Hippo armchair, with a wide and very comfortable backrest. The sofa is generously proportioned to accommodate four people.

V-Ray versions are lower than 3.1, be careful, in the materials in the BRDF section there is Microfaset GTR ( GGX ), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - whichever suits you best

For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured with PBR in mind.
