"Maybe the solution is to have a new forum for "Combined Applications", as pnevai suggested in the Lightwave forum?"

This is a good idea to my mind. I choose a gallery for my work based on the application that "feels" dominant int hat image. Usually it is Poser, sometimes Max. Having a Voluntary mixed 3D applications category would give me another option that would often be appropriate.

"Of course, as he also points out, this wouldn't merely encompass Lightwave rendering and postwork, if you used any textures created out of poser, or any props, etc.. then you would also be 'ineligible' for the Poser forum."

This is a "bad" idea.
