Hello everyone! I am currently working on a short film, where I need to composite a CGI car into a real-life environment. I was wondering if anyone could give me a hint on how to create a reflection map for the car as it drives down the street. Thank you!

A. Shoot some b-roll out the window of a car on that same street, same conditions, and then use that digatized footage as your animated reflection map.

B. Or put up huge billboards with high-quality imagery from the shoot in the back ground and let the raytracer pick up the reflections, then composite the reflective car againt whaterver the background plate looks like. You may want to composite the refelction level in multipass fashion as well for maxi control.

C. Look at 405themovie for fake car inspiration as well.
