This page provides information on the V-Ray User-defined Scalar Map.

Overview


The VRayUserScalar texture allows the user to read and return a single number value from the User-Defined properties of the currently shaded object as a result. This can be useful if the same material or texture is applied to several objects in the scene, but we want to control some of its aspects (i.e. material glossiness, or a blend between two other textures inside a Mix texture etc) with User-Defined properties.

The Example on the right uses a VRayUserScaler node to control the reflection glossiness value on a single V-Ray Material. The four different pieces of the shader ball have a VRayUserAttribute that dictates different values that drive the reflection glossiness.

User attribute name – Specifies the name of the user attribute that is looked up and returned from this shading node.
