Fire reflection?

Question

Fire reflection?

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!
