I'm currently developing my own mental ray shaders and wish to add a separate menu in the hypershade so that I can keep them all gathered in one place. Adding that menu is fine as well as adding my custom shaders to it, but since the swatch rendering in mental ray for Maya is only supported for material shaders, procedural texture shaders, sample compositing shaders, and data conversion shaders, I'm not getting any swatches for my shaders.
Is there any way to override this so that custom shaders under custom menus also support swatch rendering?
Or am I forced to keep all my shaders under the mental ray->Materials tab?
