The Nova Dot Wall Lamp makes a bold modernist statement with its chrome arching stem and spherical head—offered in polished metal or vibrant yellow for an extra pop of color. The playful yet precise design recalls retro-futurist aesthetics, while its adjustable spotlight ensures function matches form. Ideal as a reading light or accent piece, it brings a sculptural edge to any wall.

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.
