Why does Turbosquid stay in business? Here's why. Just like a movie studio has a prop house, with furniture, trees, walls, doors, props, so the set building department doesn't have to build everything from scratch, most professional CG folks have model libraries that are just like prop houses. This way they don't have to model everything in the scene, simply as a matter of saving time and effort. And if your project budget is a million plus, a few hundred bucks for a mesh isn't all that much if it saves you a day's work. And even the resources they do model themselves, they save and reuse in other projects. The CG professional's motto... If there's a way to cheat it to do it faster, cheaper, or with less resources, that's the way you do it.

Talent is God's gift to you. Using it is your gift to God.
