ALIVE
Actual Light In Virtual Environments.
ALIVE is a virtual-production workflow I developed because it didn't exist anywhere else.
A physical miniature set is lit with real LEDs in multiple lighting states. The motion-control rig scans it from every angle, and the captures become photorealistic 3D scenes via Gaussian splatting. Those scans serve as backgrounds for live-action greenscreen work — and here's the key move: the lights on the greenscreen stage are physically synchronised with the LED states baked into the scan.
The light hitting the actor is the same light that lit the model. Foreground and background match because they were never separate to begin with.
