Another real-time renderer software, Toolbag. It looks vaguely similar to Keyshot ($1000-$2000) in its simplicity and workflow, but costs only $50. Toolbag seems to be meant as a time-saving tool for videogames developers, to create early prop and character previews without having to load up an entire game world. Not quite sure why you’d need it if you have 3DXchange and iClone, but there’s a 30-day demo if you want to try it out.
