The Blender-side O-Voxel export helpers in data_processing/blender/ are
adapted from the pinned TRELLIS.2 source and retain its MIT license in that
directory. Baseline adapters under baselines/ are Fire3D integration code;
the baseline implementations are fetched separately at the revisions in
baselines/registry.json and retain their own licenses.
The model repository includes selected TRELLIS.2 decoder weights and the DINOv3 backbone required by the frozen inference protocol. Those files remain subject to their original licenses. Dataset subsets and processing adapters do not broaden the terms of SAGE-10K, InternScenes, MansionWorld, iTHOR/ProcTHOR, SceneSmith, Imaginarium, 3D-FUTURE, ABO, HSSD, or Objaverse. Consult each source and the Fire3D dataset card before use or redistribution.
