Firstly, Reality isn’t a renderer…it’s an exporter for Luxrender. Yes, lighting is different…as in a lot closer to real life.
Baked effects, in a photrealistic, physics based renderer are the worst thing to do, since the lighting/surface calculations are making the assumption that the materials are physically plausible. One of the plausible elements is energy conservation. Baking in the lighting throws energy conservation out the window.
Your best bet…match the lighting.
You should be able to do this by loading your scene in Vue and then, without the characters, just the scene, make a ‘light probe’/HDR panorama that can be used as an environment light in Luxrender. That way, your lighting will match EXACTLY, because your Vue scene is the light source for the Luxrender render.
