Can I get an animated file I can open in Blender, Unreal or Unity (mesh sequence, PLY sequence, glTF, Alembic) out of these text/image/video-to-4D systems, and what did the authors actually release?

Partially verified: the curator re-read none of the cited sources; S1, S3, S2, S12, S11, S6, S7, S5, S17, S18, S9, S4, S14 rest on the producer's pinned reading. Among the eight systems, only DreamGaussian4D documents a command-level path to a DCC tool: its README exports a per-frame OBJ mesh sequence and loads it in Blender with the Stop-motion-OBJ add-on. MAV3D describes a mesh-sequence conversion in the paper but has no available code. L4GM ships weights and code whose inference script writes only mp4 renders; a PLY writer exists in its repository but is not called, so a per-frame PLY sequence is an untested route. SV4D / SV4D 2.0 releases sample view-by-frame image grids, and no fitting or export code is visible by path name. No source read mentions Alembic, glTF, FBX or USD output. Curator qualifications: Partially verified: the curator re-read none of the cited sources; S1, S3, S2, S12, S11, S6, S7, S5, S17, S18, S9, S4, S14 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S1: HTTP 200, bytes equal to the producer pin; S3: HTTP 200, bytes equal to the producer pin; S2: HTTP 200, bytes equal to the producer pin; S12: HTTP 200, bytes differ from the producer pin; S11: HTTP 200, bytes equal to the producer pin; S6: HTTP 200, bytes differ from the producer pin; S7: HTTP 200, bytes differ from the producer pin; S5: HTTP 200, bytes equal to the producer pin; S17: HTTP 200, bytes differ from the producer pin; S18: HTTP 200, bytes differ from the producer pin; S9: HTTP 200, bytes differ from the producer pin; S4: HTTP 200, bytes differ from the producer pin; S14: HTTP 200, bytes differ from the producer pin. Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
