Nova3D generates 3D assets as executable Blender code, not opaque meshes

Code-native generation of highly programmable 3D assets (2026)

Nova3D outputs Blender source code instead of a final mesh; the compiled glTF is just an artifact. All 54 benchmark items produce a valid executable program and model, each exposing named parts and a parent-child assembly tree. It satisfies 51 of 52 numeric and count constraints (best baseline: 11), defines 59 joints across 12 assets at 98.3% geometric validity, and passes 14 of 18 blinded local edits with locality preserved in all 18. Texture realism trails baked-PBR systems, but shape quality ranks second in structured domains. The key result is representational: code-native generation bakes semantic handles in at creation time, so downstream systems can inspect, measure, edit, and animate without post-hoc segmentation or rigging.

Why it matters: Fresh idea: shifts 3D generation from 'output a surface' to 'output an editable program,' real value for game/simulation pipeline folks. But it's a fresh arXiv preprint with no product timeline and no cross-source cluster, so it lands right at the featured threshold of 72.
