Fire reflection?

Question

Seeking advice on best way to special effect the reflection of fire on glass...
In the scene a woman is inside, looking out window.  The script calls for a huge bonfire outside.
I need to see the fire's reflection on the inside of the window....  (camera inside looking at woman and window)
And I need to see the fire's reflection on the outside of the window...  (camera outside looking at woman through window)
I need not get too fancy but it would be great if on a closeup of the woman's face, I could put fire reflected in her eyes... (tracking motion?)
Any advice would be greatly appreciated.

Motion makes this fairly easy with the "reflections" setting for objects.  Create a 3D scene, place the fire and a rectangle for the window.  Under the properties tab, select Reflection and adjust the reflectivity, blur, and falloff values.  Experiment with the blend mode for best effect.  If you actually have a video of the scene, then the easiest way is to overlay a video clip of a fire on top of your video, or by using a fire particle generator - size it to fit the window and play with both opacity and blend modes.  Match Move behavior works pretty well on eyes, and i agree that's how I would handle that reflection.  I used that to put a hologram in a scene.  The camera was hand held so the problem was that the hologram stayed fixed in the middle of the scene while everything else was moving around a bit. So I added a match move behavior and had the hologram track with the desk the person was sitting at.  Good luck!
