How does the compositing phase enhance the final look of 3D models?

The compositing phase enhances the final look of 3D models by integrating rendered 3D elements with 2D graphics, effects, and color adjustments, creating a cohesive, visually polished result. It merges key layers—such as shadows, reflections, and atmospheric effects—to ensure these elements align naturally with the 3D model, boosting realism or stylization based on project needs. Compositing also balances lighting and color across all elements, refining contrast and hue to unify the scene, making the model blend seamlessly with its environment. By adding post-processing steps like opacity tweaks, filter applications, or edge detail refinements, compositing further elevates visual impact, resulting in a professional, polished final look.
