Well it boils down to...your imagination, kinda like fixing a car sort of, I may not have the right tools at the time, but its time to get creative and improvise. All the stuff you see in movies isn't done by one application its done by many, I and 2 others almost got to work on Lord of the rings 2 with WETA to teach the visual effects guys how to use Mojoworld for back drop images, but they were to far into post production so it was cancelled.:-(

Do atleast one thing a day that scares the hell outta ya!!
