Got the solution from support and thought I'd post it here in case anyone
else runs into this.
For plugin-based custom shaders, the equivalent to setting the 'ui
"mapping"' in an SPDL is to set a special undocumented attribute on the
ShaderParamDef. The attribute name
is {8C80DEF3-1064-11d3-B0B7-00A0C982A112} and the value is the GUID for the
viewport ambient/diffuse/spec/whatever (you can find those from the
softimage SPDL by searching for ui "mapping")
Example:
inputParamDefs.GetParamDefByName(L"diffuse").GetAttributes().Set(L"{8C80DEF3-1064-11d3-B0B7-00A0C982A112}",
L"{3515CC72-082C-11D0-91DE-00A024C78EE3}");
