How much is it? What software does it work in?

HDR light studio has been around for years.. it has a standalone renderer for preview and a lot of similar functionality as keyshot. If you are doing product rendering for print images, or have experience with real studio lighting, its a great tool. It has basically nothing to do with game dev.
