v9.0 (2011)
ICE Shaders
Returns or sets the symbol name of the shader code to execute as
a String. The symbol name is the
name of the procedure to execute (for example, "material-phong_cg"
is the symbol name for the Softimage Phong shader's Cg renderer).
This is the same information as specified in the Name entry under
the MetaShader > Renderer section in a SPDL file.
If the symbol name hasn't been set then an empty string is
returned.
