New to Lumion - GI Lighting in Lumion 3?

Hello,

I'm new to Lumion and am loving it so far! It's so easy to use, it's refreshing :-)
I have a question about the lighting in the sample scenes. It looks like GLobal Illumination, but doesn't react to changes in the objects. For instance, there is a scene with a big red sunshade, and this creates a nice red spot on the ceiling, but when I replace the red sunshade with a green object, the spot is still red. How come?

Is this what the new lighting in Lumion 3 is going to be about?

Thanks!

In v2 and that scene, no GI, its faked by using a light to emit red.

Lumion weblog: Lumion 3 Preview: latest news:

"Global illumination preview

In Lumion 3.0 a new feature which automatically reflects light as it hits a surface.
 
The effect is viewable in real-time so you can directly see the change as you modify materials or lighting.
 
For example you can have a room with a green floor and it will light up green. Point a light at a red sofa the reflected light will illuminate the room with red light."

Oh, I see, this is some kind of a cheat then?
I'm glad to hear Lumion 3 will address this. Have you tried LumenRT? The pictures it creates are very beautiful. I downloaded the demo, but it looks like it only works with Sketchup though  :(
