Real-time Bridge

The feedback loop in traditional rendering is measured in minutes or hours. A lighting change might take 30 minutes to render, and you won't know if it works until you see it. Multiply that by dozens of iterations, and you've lost a day to waiting.

Real-time rendering compresses this loop to seconds. Unreal Engine 5's Lumen provides global illumination at 60fps—not final quality, but close enough that lighting decisions made in real-time translate faithfully to final renders. Path tracing mode bridges the gap even further, providing ground truth at interactive rates.

The workflow: iterate in real-time until the creative intent is locked, then export to offline renderers for final quality. The lighting intent survives the translation because the physics are consistent.
