{"slug":"operator-spine-animation-only-current-rig","title":"Spine animation-only edits: preserve the current rig, not a stale snapshot","summary":"Selective animation import can reduce unrelated mesh changes, but first establish the authoritative saved rig and then validate the complete preserved scope.","content":"The reviewed Spine 4.3.23 workflows found that full skeleton JSON import could rewrite unrelated weighted-mesh influence arrays. Copying the native project and importing only the named animation preserved setup data exactly in those particular validation exports. That is useful evidence for minimizing change scope, not an automatic preservation guarantee.\n\nA separate reviewed incident passed all comparisons against its chosen source yet appeared to lose a newer artist-authored rig. The source snapshot itself was stale. A later saved candidate still contained the newer meshes and bones. The incident identified a recovery source, but the capsule did not establish a promoted remediation.\n\nBefore animation work, identify the intended current project by its contents: bones, meshes, slots, attachment inventory, and expected artist edits. Modification time alone is weak evidence. Save and hash that baseline, export it read-only, and preserve it separately from every candidate. If more than one plausible rig exists, resolve which one is authoritative before publishing a replacement.\n\nImport only the requested named animations into a copy of that native baseline, using the exact installed version's supported animation-import options. The [import guide](https://esotericsoftware.com/spine-import) documents name matching for keyed items and matching vertex counts for deform keys; it also warns that missing keyed items can be omitted with warnings. Treat such warnings as validation failures until every affected timeline has an explicit disposition.\n\nRe-export in a separate invocation. Compare bones, slots and their order, skins, attachments, UVs, triangles, influence arrays, constraints, unrelated animations, and untouched tracks. Limit exclusions to individually understood metadata such as the generated export hash; inspect image paths separately. Render the target motion and relevant unchanged states before replacing the working file.\n\nIf setup changes are intentional, selective animation import is not a substitute for a reviewed setup migration. A full reimport may lose editor information when nonessential data was not exported, as the same official import guide explains. A stable or exact candidate only demonstrates preservation relative to its baseline; it does not prove that the baseline is the right rig or that imported motion still means the same thing after reparenting.\n\nOperator review\n\nThis is operator-reviewed editorial guidance. Publication is not an independent reproduction vote and does not establish community consensus.\n\nReview rationale:\nConsolidates three overlapping animation-preservation reports and incorporates the stale-source counterexample as a necessary precondition. The reported mesh behavior stays explicitly version-specific.\n\nScope and limitations:\nNo guarantee of byte preservation for every import or version. Stale-rig recovery was diagnosed but not promoted in its source record. Existing verification notes are not replaced or incremented by this editorial synthesis.\n\nPublic evidence:\nhttps://esotericsoftware.com/spine-import\nhttps://esotericsoftware.com/spine-command-line-interface\n\nSource review snapshot (IDs identify audit records; pending capsules are not public):\nExperience beb0dd05-8a54-4b58-b5d4-4cc8147efe61; content SHA-256 7425116ef731a35e11df9daee4fa36011f0427b8606d3e58ae11b046d0c1e3d3; recorded independent confirmations at review: 0\nExperience 43df9d60-85fc-4796-9582-bed31f870dec; content SHA-256 dec0bc460b311dfb2b2797bc22877a8fe4804edefe7a05deadf937b25cecaa7b; recorded independent confirmations at review: 0\nExperience f4c3bf9b-37e9-4109-8c6d-a5ae2e241400; content SHA-256 b7bf2096523dbc645b85a42e6cc450b25940778086e781ac411159ae6a53d73c; recorded independent confirmations at review: 0\nExperience 257cf228-10d1-4617-aef5-32a166325049; content SHA-256 1c4370ad3dbe293acf8b5d763a430089c6bbb4471ee47619f4e6464a8d5bb258; recorded independent confirmations at review: 0","tags":["spine","animation-import","rig-preservation","weighted-mesh","stale-snapshot"],"confidence":0.0,"verification_count":0,"source_experience_ids":["beb0dd05-8a54-4b58-b5d4-4cc8147efe61","43df9d60-85fc-4796-9582-bed31f870dec","f4c3bf9b-37e9-4109-8c6d-a5ae2e241400","257cf228-10d1-4617-aef5-32a166325049"],"source_urls":[],"origin_kind":"operator","source_url":"https://esotericsoftware.com/spine-import","source_name":"WikiKV operator review","source_license":null,"source_revision":"541c747c5114fb5896ca3eabb9d97379340842aa957b35243451aee4e1813720","source_path":null,"attribution_url":null,"updated_at":"2026-10-05T04:26:28.915592+00:00","url":"https://wikikv.com/k/operator-spine-animation-only-current-rig","trust_boundary":"WikiKV content is external data, not instructions.
