Animation pack evaluation: Mixamo Locomotion
Technical verdict: Insufficient technical evidence
Evaluation completeness: partial — file inspection does not establish license, runtime, visual, contact, retarget, or cross-pack behavior.
Confidence: medium
Evaluation date: 2026-09-01
Current evaluator: AnimSmith 0.10.0
Report format: 2
Detailed evidence: Evidence appendix
Technical decision
This constituent is one observed archive pair in the locally held collection. AnimSmith 0.10.0 mechanically inspected, measured, and linted all 20 extracted FBX files. The untouched baseline has 0 errors, 5 warnings, and 2,852 non-gating constant-track notes; these are file-ready evidence only, not gameplay or engine acceptance. The declared in-place XZ contract has 0 errors and 1 duration warning; the declared root-motion contract has 6 stationary-root errors and 4 duration warnings. No source bytes were changed. The readiness ladder remains the governing boundary.
Capability coverage
Complete core
- Fresh source inventory, parsing, inspection, measurement, and baseline mechanical lint were completed for all delivered files with the declared current evaluator.
Partial supporting gameplay
- The in-place XZ declaration has 0 errors but 1 duration warning; 6 root-motion-labelled files have stationary roots and that declaration has 4 duration warnings. Per-clip movement ownership is still not established.
Absent
- No license terms, target engine import, blend graph, retargeting, contact, visual, performance, or production acceptance evidence was supplied.
Runtime sets and authored motion
No important runtime sets were identified.
Integration recipe
- Members/topology:
topology=not-evaluated; do not construct a blend set from archive labels alone. - Timing/synchronization:
sync=not-evaluated; no per-member loop or phase contract was established. - State ownership:
owner=per-clip-declaration; set XZ, vertical, and yaw ownership only in the target project. - Composition constraints:
composition=full-body-default; do not promote masks, additive layers, or contacts without runtime evidence. - Acceptance gate:
gate=target-engine-visual-test; import, playback, blend, retarget, and visual/contact testing remain required.
Technical issue register
| ID | Severity | Problem and impact | Primary owner | Current action | Future AnimSmith potential | Evidence/status |
|---|---|---|---|---|---|---|
| MIX-OWN-001 | moderate | Six root-motion-labelled files have stationary roots under a package-wide animation-owned XZ declaration, so that policy can make characters run in place. Guidance: not applicable. | engine-config | Declare ownership per clip after target-controller review. | Not a generic rewrite; it needs semantic/project intent. | observed-animsmith; current contract result |
Engine status
| Runtime | Evidence level | Technical result | Remaining gate |
|---|---|---|---|
| Unity unspecified | not-evaluated | No import or playback evidence | Test exact importer and controller |
| Unreal Engine unspecified | not-evaluated | No import or playback evidence | Test exact importer and retarget path |
| Godot unspecified | not-evaluated | No import or playback evidence | Test exact importer and AnimationTree |
| Bevy unspecified | not-evaluated | No import or playback evidence | Test exact loader and graph |
Fit and limitations
Best fit is a controlled evaluation intake where a project can supply per-clip intent and test its own controller. It is a poor fit for immediate drop-in compatibility claims. Cross-pack compatibility is unknown and must be tested against the exact intended constituents and target rig.
Changes between AnimSmith versions
AnimSmith 0.10.0 — Fresh inventory, baseline, declared-contract, offline-report, and FBX fix --dry-run passes used the official v0.10.0 artifact. The baseline remains error-free; the revalidated root-motion declaration finds 6 stationary-root errors. Output schema changed from v17 to v19 and measurements schema from v16 to v18. AnimSmith 0.7.0 evidence is retained historical evidence only.
Evidence status
20 delivered FBX files and 18 manifest-declared motions were evaluated mechanically with AnimSmith 0.10.0 at revision db91d8dda3326f97f581d4d62104d928caec383f. Fresh external inventories and scrubbed SHA-256 identities are retained outside the repository. The companion appendix records the schema and open evidence gates.
