That doesn’t mean that there aren’t cheaper or free alternatives available. Many of the newest and most impressive rendering engines require a high production budget that most small studios and creators simply cannot afford. Even after all of this, there is still one final consideration - whether or not you are willing to pay for the licensing fees. Each rendering engine has its own features, capabilities, and limitations furthermore, some can only be accessed online, some are integrated, and others are standalone applications. And it is not a simple decision as no two engines are the same.
Whether you are a game developer, artist, or editor, the rendering engine is always one of the most important considerations when building a model or scene.
