A realistic bouquet of garden flowers in a ceramic vase. White and pink cosmos. Physical Material and Double Sided were used for the textures. Those working in V-Ray versions lower than 3.1 should be careful; the materials in the BRDF section have Microfacet GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
