Lighting-grounded Video Generation with Renderer-based Agent Reasoning

CVPR 2026

Diffusion models have achieved remarkable progress in video generation, but their controllability remains a major limitation. Key scene factors such as layout, lighting, and camera trajectory are often entangled or only weakly modeled, restricting their applicability in domains like filmmaking and v
