Video captions: Create a velvet material and assign it to your geometry. The Diffuse Color defines the diffuse base color of a material. The Roughness controls the roughness of the material. The smaller the value, the sharper the highlight. The higher the roughness, the more diffuse and softer the reflection of light behaves on the material. Darkening controls the intensity of the diffuse component. Values above 1 darken the material, while the values below brighten it up. All this is linked to the viewing angle. The more directly you look at a face, the less this effect becomes visible. Falloff controls the glossy component, which is dependent on the viewing angle and effects the edges of objects.
