MolmoSpaces
This respository contains asset data for MolmoSpaces, including
- Objects
- Robots
- Scenes
- Grasps
- Benchmarks
Updates
[2026/02/16] - Isaac-compatible USD objects and scenes now also available!
Downloading
We recommend using the download.py script to list available data sources and extract data from one or all sources to a local cache directory. To use the script you'll need a few dependecies in your Python environment that can be installed, e.g., by:
pip install zstandard datasets huggingface-hub tqdm

The included metadata (downloadable from the mujoco/objects/objathor_metadata/20260129 source) provides the license for each object in the Objaverse subset.
We note that Objaverse models have been significantly modified to reduce memory and processing requirements, including mesh decimation, convex collider extraction, and baking of visual effects via Blender scripts, so the provided quality may not reflect the original model.
