Is There a One Pass Per Item?

The team of us would run in to try and expedite enough for time purposes. On a film like this,. they knew how much environment was going to be created, didgly? So they took the time to do it. But on a lot of films, the visual effects department has to fight for things like this... And so it's interesting to me now, even even doing films after infinity war and end game, how hard the visual effects departments have to fight. "I'm very, very good at it. I've done it, like, i don't know, thousands and thousands of times"
