 If you want some high-res textures, you can set `--device` to `a6000` for 3k resolution. To play around other parameters, please check `scripts/generate_texture.py`, or simply run `python scripts/generate_texture.py -h`.
 
+## Benchmark on Objaverse subset
+
+To generate textures for the Objaverse objects we used in the paper, please run the following script to download and pre-process those meshes:
+
+```shell
+python scripts/download_objaverse_subset.py

+
+All pre-processed meshes will be downloaded to `data/objaverse/`.
