-The **MTU3D dataset** provides all the necessary data for reproducing the experiments in the [Move to Understand a 3D Scene: Bridging Visual Grounding and Exploration for Efficient and Versatile Embodied Navigation(ICCV25)](), including **stage1 data for embodied segmentation training**, **feature saved from stage1** and **vle data**.

-**SceneVerse** required for **MTU3D** should be downloaded from [SceneVerse](https://github.com/scene-verse/sceneverse?tab=readme-ov-file). 
+The **MTU3D dataset** provides all the necessary data for reproducing the experiments in the [Move to Understand a 3D Scene: Bridging Visual Grounding and Exploration for Efficient and Versatile Embodied Navigation(ICCV25)](https://www.arxiv.org/abs/2507.04047), including **stage1 data for embodied segmentation training**, **feature saved from stage1**, **vle stage2 data** and **embodied_bench_data**. 
 
 Specifically, we provide the correspondence between **\*.tar.gz** in this Dataset and **data.\*** in the config file:
 
-| .tar.gz | data.config |
-| --- | --- |
-| embodied_base.tar.gz | data.embodied_base |
-| embodied_feat.tar.gz | data.embodied_feat |
-| embodied_vle.tar.gz | data.embodied_vle |
+| .tar.gz | data.config | description |
+| --- | --- | --- | 
+| embodied_base.tar.gz | data.embodied_base | stage1 data |
+| embodied_feat.tar.gz | data.embodied_feat | feature saved from stage1 |
+| embodied_vle.tar.gz | data.embodied_vle | vle stage2 data |
+
+The **embodied_bench_data.tar.gz** is used to change `data_set_path` and `navigation_data_path` in hm3d-online/*.nav.py.
 
 
 > 📌 The dataset is large and stored in split archives. Please **download all parts**, **merge**, and **extract** them before usage.
