VFX with Natron - E0087 - Eye Effects Part 2 - Simple Tracked Eyes
In this episode we are first going to finish up the glow fade that was skipped at the end of the last episode, and continue on from there to explore tracking eye effects and why if the eye effect is a simple one I think rotoscopes are potentially a better opinion; however, there are times when a simple roto won't be enough and then tracking becomes an aid, but it also can present new issues. We are not going to focus heavily on the issues, but the basics of how one builds a simple eye tracking solution for more complex eye effects.
