RedshiftUserDataVector Shader

Arnold provides its own shader to read and return vector user data: RedshiftUserDataVector. This data can be used to feed other shaders in Maya that have a vector or color input. Refer to the Shader Attributes page to know how to store vector user data in a mesh.


Result of a Get User Data Vector Shader combined with a Surface Shader and different user data values.

Creation

To create a RedshiftUserDataVector, the Redshift plugin must be loaded.

  • Hypershade: Redshift / Shader / Utility / RedshiftUserDataVector
  • MEL command: createNode RedshiftUserDataVector;

Configuration

Vector Attr Name Name of the vector user data attribute to read in the rendered mesh. The name of the user data should be the same than the one defined in the Shader Attributes of the Mesh.
Default Value Default value to return if no matching user data was found in the Character File

Shading Graph Integration

Their Shading Graph integration is similar to the Mental Ray shaders: GetUserData Vector
