The shaders in this section are unsupported and they can no longer be accessed directly from the Softimage user interface. For example, these shaders are not displayed in the preset manager and they are not available from the Nodes menu in the render tree. However, many of these shaders are still installed with Softimage to provide compatibility with older scenes that use them. It is recommended that you replace any unsupported shaders in your scenes and apply equivalent shaders from the current Softimage shader library.
