HyUU has a utility that Helps expand the input options with Bifrost in Maya.

This new downloadable utility for Maya Bifrst from HyUU does two things the first is input sets, and the second is Bobify. An input set is an object set that acts like an input to a Bifrost Graph.

The utility can add and remove objects from the set if you duplicate an object; it’s automatically added to the graph same thing as deleting objects. Also, shading groups are just another kind of set, so you could use one of these as an input set, allowing the assignment of materials to control what’s in the graph.

Bobify will convert an arbitrary Maya node with attributes to a Bifrost Object. For example, you can take a Maya Camera and ‘Bobify’ it, and it will become a node in a graph with all the attributes you select.
