+# Light-X: Generative 4D Video Rendering with Camera and Illumination Control
+
+This repository contains the official model for the paper [Light-X: Generative 4D Video Rendering with Camera and Illumination Control](https://huggingface.co/papers/2512.05115).
+
+Light-X is a video generation framework that enables controllable rendering from monocular videos with both viewpoint and illumination control. It proposes a disentangled design that decouples geometry and lighting signals, and introduces Light-Syn, a degradation-based pipeline, to synthesize training pairs from in-the-wild monocular footage.

+## Abstract Summary
+Light-X is a video generation framework that enables controllable rendering from monocular videos with both viewpoint and illumination control. It tackles the trade-off between lighting fidelity and temporal consistency by proposing a disentangled design for geometry and lighting signals, and addresses the lack of paired multi-view and multi-illumination videos through a degradation-based pipeline called Light-Syn.
+
+## Installation
+To get started with Light-X, clone the repository and set up the environment:
+
+```bash
+git clone https://github.com/TQTQliu/Light-X.git
+cd Light-X
+conda create -n lightx python=3.10
+conda activate lightx
+pip install -r requirements.txt
+```
+
+## Inference
+You can run inference using the provided `run.sh` script. All required models will be downloaded automatically.
+
+```bash
+bash run.sh
+```
+For more detailed arguments and examples on camera and relighting control, please refer to the [official GitHub repository's inference section](https://github.com/TQTQliu/Light-X#%EF%B8%8F-inference).
