The V-Ray Proxy allows to add Displacement on Entities geometry to add details at render time. At render time, displacement will be assigned the same way than surface shaders: the render plugin will look for a VRay Displacement Nodes with the same name than the one set in the Character File and assign it to the created geometry. Some parameters can be override from the Character File (see below)

Examples of Displacement Mapping with different displacement amounts


Displacement Shaders are created automatically when a displaced mesh is imported to the character geometry mapping.
However, a Displacement Shader can be added manually:
  • open the Character File in the Character Maker and go to the Geometry Tab
  • select the Mesh you want to displace in the Main Workspace
  • drag and drop a Shader Node from the Asset Nodes tab
  • enter a name for the Shader
  • enter "displacement" as the category of the Shader

Example of a Displacement Shader applied to a Shading Group Node


It is possible to configure a Displacement Shader by linking to the Shading Group Node some specific Shader Attributes. Here are the supported Shader Attributes (those parameters are the same attributes defined by V-Ray for each mesh in Maya):

Attribute Name Type Description
displacement_amount float Determines the maximum displacement amount which occurs at places where the displacement map is white. (notice that this value can also be controlled with a ppAttribute).
displacement_shift float Adjusts the whole displacement map up and down. The effect will be to expand (for positive shift values) or shrink (for negative shift values) the displaced surface (notice that this value can also be controlled with a ppAttribute).

Notice that Displacement quality can be controlled from the Render Proxy.
