Missing AETemplates for mental ray

Maya
1

I don't have in my Attribute Editor some options for mental ray materials (shader, textures).

Can anyone help me?

I suspect that I don't have the AETemplates for mental ray nodes because I see that Maya search something when I open the Attribute Editor.
See the script editor output:

"editMenuUpdate MayaWindow|mainEditMenu;
ShowAttributeEditorOrChannelBox;
if(isAttributeEditorVisible){setChannelBoxVisible(1); }else{openAEWindow;};
listHistory -pdo true -lf false -il 2 "dgs_material1";
// Result: dgs_material1 //
listHistory -pdo true -lf false -il 2 -f true "dgs_material1";
// Result: dgs_material1 defaultShaderList1 //
exists AEdgs_materialTemplate;
// Result: 0 //
exists AETHdependNodeTemplate;
// Result: 0 //
exists AETdependNodeTemplate;
// Result: 0 //
exists AETnameObjectTemplate;
// Result: 0 //
setUITemplate -pst attributeEditorTemplate;
// Result: attributeEditorTemplate //
"

But I don't have "AEdgs_materialTemplate" and the rest...

Thanks
