It appears that once HDR Shop/Light Gen has generated lights and shadows for Houdini that we load the information via the object layout using the textport, saving the whole thing as a .hip scene. Can anyone confirm this or correct me? I'm planning on trying this out sometime this week.
Thanks in advance-

Yes.

from LightGen page [ict.usc.edu]

Source the resulting file into HScript. It will add the lights to the scene description. It also generates a variable called “lightgen_dimmer” that can be used to dim all of the lights simultaneously.
