So this weekend I wanted to figure out a way to get a "Tron" type effect using the CGI shoe as a base. Pretty happy with the results. Set it in a mirror box, layered back in the solid CGI shoe for realism and added some particles to liven it up a bit. Toyed with blurry reflections but I enjoyed the sharpness of this more.
I also made use of the Sabertooth render passes tutorial I posted below which was super helpful. I set up a render with particles, one without so I could get a clean shoe and one with the real shoe on. That saved a ton of time by being able to click through them and make sure it all works and fire off one render. The only big problem with render passes though is that it does not support network rendering so no render farm when using it.
