From Concept to Final VR Scene. Here is an early concept and a frame from Invasion! You can see that we kept the very painterly style all the way until the end. This is particularly due to the fact that we were a start up with no money and strict time constraints BUT it was also because we were curious of how it would feel to be inside of a classic 2D cartoon. Would the audience believe it? In the end about 80% of the VR environment was hand painted onto shaped cards.
