CompoScene will help you create and export SketchUp scenes with rendering channels for compositing in Photoshop or other painting apps.
There are many rendering apps out there, but self-expression can only ever come from you. If you let the software take over then you're in danger of composing renders that clone the same look dictated by the app and not you.
CompoScene creates rendering channels for you to build upon and create your own art style.
