10.48550/arXiv.2603.26546A feed-forward framework for 3D-aware weather editing in autonomous driving videos, enabling fine-grained physical control without massive datasets.
Abstract
Generative video models have significantly advanced the photorealistic synthesis of adverse weather for autonomous driving; however, they consistently demand massive datasets to learn rare weather scenarios. While 3D-aware editing methods alleviate these data constraints by augmenting existing video footage, they are fundamentally bottlenecked by costly per-scene optimization and suffer from inherent geometric and illumination entanglement. In this work, we introduce AutoWeather4D, a feed-forward 3D-aware weather editing framework designed to explicitly decouple geometry and illumination. At the core of our approach is a G-buffer Dual-pass Editing mechanism. The Geometry Pass leverages explicit structural foundations to enable surface-anchored physical interactions, while the Light Pass analytically resolves light transport, accumulating the contributions of local illuminants into the global illumination to enable dynamic 3D local relighting. Extensive experiments demonstrate that AutoWeather4D achieves comparable photorealism and structural consistency to generative baselines while enabling fine-grained parametric physical control, serving as a practical data engine for autonomous driving.

WHY NOW
Generative Video moved forward this cycle; last verified April 2026. Public score 7.0/10. Production flags indicate code availability.
At the core of our approach is a G-buffer Dual-pass Editing mechanism. The Geometry Pass leverages explicit structural foundations to enable surface-anchored physical interactions, while the Light Pass analytically resolves light transport, accumulating the contributions of local illuminants into the global illumination to enable dynamic 3D local relighting.
This is a core statement of the paper's contribution, directly from the abstract.

Extensive experiments demonstrate that AutoWeather4D achieves comparable photorealism and structural consistency to generative baselines while enabling fine-grained parametric physical control, serving as a practical data engine for autonomous driving.
The abstract states this, and Table 3 provides quantitative metrics supporting this comparison.

We evaluate on 120 scenes from the Waymo Open Dataset [33], specifically using NOTR — a versatile subset of Waymo encompassing diverse driving scenarios, as surveyed in [72].
This is a specific detail about the experimental setup mentioned in the analysis section.

Existing 3D-aware weather synthesis frameworks [10,26] are fundamentally constrained to static scenes, rendering them structurally incompatible with the highly dynamic environments of autonomous driving.
This is stated as a limitation of prior work, motivating the need for AutoWeather4D.
