I've got a business idea I'm trying to make a few renders for, and I've got things somewhat set up in SketchUp. I looked for free renderers, and the only decent one I found was Kerkythea. Is anyone around here familiar with Kerkythea, or does anyone have better suggestions? I'd like to be able to do "advanced" things (meaning I don't know how to do them) such as light cones (like you'd see in dusty air in a movie theater).
In case it matters, the renders would all be internal, architectural renders of facilities, not external, sky-lit gardens or anything like that (although the building might have small plots of greenery like you might find in a mall).
