Brief

Researchers have developed PIXLRelight, a novel feed-forward system for controllable single-image relighting. This approach bridges physically based rendering with learned image synthesis by utilizing shared intrinsic conditioning derived from either real photos or PBR renders. The system decomposes images into albedo, diffuse shading, and residuals to condition a transformer-based neural renderer, enabling arbitrary PBR-style lighting control with high image detail preservation. PIXLRelight achieves state-of-the-art quality and operates in under a tenth of a second per image. AI
