-🚀 [2024/6/8] [Material library annotations](#📦-data-preparation) generated by GPT-4V and [data engine](#⚡-quick-start) are released!
+✨ [2025/3/12] The [inference code](xxx), [project page](xxx) and [huggingface demo](xxx) are released!
 
-🚀 [2024/4/26] The [paper](https://arxiv.org/abs/2404.16829) and [project page](https://sunzey.github.io/Make-it-Real) are released!
+✨ [2025/1/27] We release the [paper](https://arxiv.org/abs/2501.16330) of RelightVid!
 
 ## 💡 Highlights
 - 🔥 We first demonstrate that **GPT-4V** can effectively **recognize and describe materials**, allowing our model to precisely identifies and aligns materials with the corresponding components of 3D objects.
