In a Plug-In Manager there were three plugins: mtor, mtorsubdiv and RenderMam_for_Maya. They are loaded well. The Output Window writes nothing. In the Render-RenderUsing menu has appeared new line: Renderman. It even renders. Has appeared a "Renderman" menu, but in it nothing works. At activation of any item nothing occurs. I have the question - is normally? What it is necessary to make that something occured?
