Do the Objaverse-trained 4D generators (L4GM, SV4D, SV4D 2.0, Diffusion4D) say whether their training data overlaps the Consistent4D benchmark objects, and what should an agent assume when comparing their scores?

Partially verified: the curator re-read none of the cited sources; S14, S13, S9, S5, S15, S16, S8 rest on the producer's pinned reading. The Consistent4D author states that six of the seven benchmark objects are in Objaverse and recommends filtering them from training. A set intersection I ran (synthesis, not executed code from the repositories) finds 6 of the 7 benchmark uids in a 37,789-ID list of animated Objaverse-1.0 objects published in the Diffusion4D repository, matching that statement. SV4D states it excluded the benchmark objects; L4GM v1 states that it renders all animated Objaverse 1.0 objects and evaluates on the benchmark, and the passages searched contain no exclusion statement; SV4D 2.0 v3 contains no such statement in the strings searched. Overlap is therefore an open question for L4GM, and possibly SV4D 2.0, on this benchmark, not an established fact: L4GM filters videos by motion, and the L4GM training list is not in its repository. Curator qualifications: Partially verified: the curator re-read none of the cited sources; S14, S13, S9, S5, S15, S16, S8 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S14: HTTP 200, bytes differ from the producer pin; S13: HTTP 200, bytes equal to the producer pin; S9: HTTP 200, bytes differ from the producer pin; S5: HTTP 200, bytes equal to the producer pin; S15: HTTP 200, bytes equal to the producer pin; S16: HTTP 200, bytes equal to the producer pin; S8: HTTP 200, bytes equal to the producer pin. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
