VFX on a Green Screen?

In these particular cases with our shots and the sequences, we replaced all of the background and only used the LEDs for interactive lighting on the characters. We either painted it out, replaced the body armor or his costume with all CG in some cases. And then matched what was on set with the interactive light that we're seeing on his head onto the suit, onto the characters, onto the background with the lightning. The LED wall can produce in real time what's required to match the camera movement. For a DMX on set, you could actually go ahead and press on a trigger and you would have constant lightning and we had it on a loop.
