I am curious what kind of options are available in Houdini or via 3rd party scripts/plugins in Houdini for doing exact outline placements(think line-inking) on a edge (i.e. select edge set option for an outline perhaps with a falloff on the stroke) and being able to via weight map or other map type specifically set location and mask off certain areas for cel/toon shading to define the shadowed/highlighted areas as oppose to being stuck using a generic ramp setup.
