As a matter of fact. There is a small distinction: while we refer to the same engine and/or executable mantra, meaning the Houdini renderer as opposed to rman (RenderMan) or mray (mental ray), in Houdini UI runtime parlance we refer to mantra as render(er|ing) without VEX shaders taken into account, and obviously to vmantra with VEX shaders.
