SimCode4D: Code2Worlds-2 development benchmark
SimCode4D DEV15 is the public, portable 15-case development benchmark for the Code2Worlds-2 paper. It covers indoor, industrial, natural outdoor, service, and urban environments, with three cases in each domain. The benchmark tests whether a generated world builds and whether its physical behavior satisfies the registered task, integrity, mechanics, kinematics, contact, friction, and safety checks.
The validation split in the viewer is a case index. Each row points to
the complete frozen specification, gold predicates, physical profile, task
confirmation, and runtime artifacts in this repository. It is not a table of
model outputs or experiment results.

The runtime package is copied from the public
Code2Worlds-2 repository
at commit ca35f25cda19aadf1d211ae3e55e390905507f1d. Paths are preserved so
that the original registry, hashes, and evaluator work without rewriting the
cases. The case index is an additional convenience file.
Download and verify
Use Python 3.10. From the downloaded dataset root:
hf download AIGeeksGroup/SimCode4D --repo-type dataset --local-dir SimCode4D
cd SimCode4D
python -m pip install -r requirements-benchmark.txt
python benchmark/simcode4d_unified/check_public_release.py
The integrity check verifies the frozen references and loads all 15 compiled
M1 worlds and runtime models with MuJoCo. The expected output has "passed": true and "case_count": 15.
To test the submission interface without generating a new world:
python benchmark/simcode4d_unified/tools/make_reference_smoke.py \
--output /tmp/simcode4d-reference-package
python benchmark/simcode4d_unified/tools/score_submission.py \
--submission-root /tmp/simcode4d-reference-package \
--output /tmp/simcode4d-reference-score \
--case-ids SER-03-hotel-drawer --physics-seeds 401
This is a reference-interface smoke test, not a generated-method score. See the benchmark README for the full matrix, method submission format, and metric definitions.
Scope and provenance
The registered reference matrix contains 15 cases × 3 deterministic rebuild slots × 5 physics seeds = 225 executions. The three rebuild slots do not represent independent generated worlds; there are 75 distinct case-physics trials. The reference-probe results described in the benchmark README check benchmark self-consistency and must not be presented as a Code2Worlds-2 model score or as a held-out leaderboard.
This portable release excludes archived Blender authoring scenes, ablation configurations, completed run logs, leaderboards, and demo videos. The original authoring sources for three indoor scenes were unavailable. Three cases have path-only asset portability repairs; see PORTABILITY.md. The source-name binding metric requires authoring-source catalogs outside this compact release; the included runtime binding check uses compiled model interfaces.
No repository-wide license was specified in the source release. Third-party
model assets retain their license and notice files under vendor/; review
those notices before reuse beyond the benchmark runtime.
