 This dataset contains various 2D and 3D files obtained by processing meshes from
 [PartObjaverse-Tiny](https://huggingface.co/datasets/yhyang-myron/PartObjaverse-Tiny). It consists of the following:
 
-- `PartObjaverse-Tiny_single_view_render.zip`: Single-view PNG renders of the objects in PartObjaverse-Tiny, rendered using this script: [blender_render_16views.py](https://github.com/Pointcept/SAMPart3D/blob/main/tools/blender_render_16views.py)
+- `PartObjaverse-Tiny_single_view_render.zip`: Single-view PNG renders of the objects in PartObjaverse-Tiny, rendered using this script: [blender_render_img_mask.py](https://github.com/HKU-MMLab/OmniPart/blob/main/dataset_toolkits/blender_render_img_mask.py)
+- `PartObjaverse-Tiny_2d_seg.zip`: Ground-truth 2D segmentation of the the PNG renders, created using this script: [blender_render_img_mask.py](https://github.com/HKU-MMLab/OmniPart/blob/main/dataset_toolkits/blender_render_img_mask.py).
+  Each object in the 3D scene geometry is considered a different segment. The `seg.exr` files assign an integer to each segment (0 = background).
+  The `seg_vis.png` files are colored, human-readable images of the segmentation.
 - `PartObjaverse-Tiny_mesh_colored.zip`: Meshes from PartObjaverse-Tiny, colored according to semantic part label using
   [20 visually distinct colors](https://sashamaps.net/docs/resources/20-colors/) for visualization purposes.
   These colored meshes can be viewed on [Streamlit](https://partobjaverse-tiny-visualizations.streamlit.app).
