XSI, and maybe others, has a feature where you can plug-in your game engine to use directly in the 3D viewport. So what you see in XSI is exactly what it will look like in your game. Though I'm guessing this won't work at all with Blitz3D, as you can't (as far as I know) easily plug Blitz3D into XSI. So it's kind of useless for us.
Or to quote their website. "Using the integrated, programmable display pipeline and realtime shaders in XSI allows developers to author and import game shaders directly in XSI, where artists can validate them on characters and props in any viewport."
