Went to source animationClips[] and found two things: a bug in what 5.3.91 committed, and a naming trap that has already cost BT411 a shipped defect. THE BUG, MINE. I sized animationClips[AnimationCount] -- 0x1d, from the enum. Wrong. The name table stops at 0x1d but the ARRAY does not: slot 0x20 (mech+0x64c) is the bump/crash clip the mech binds on a hard wall impact. So the array is [AnimationSlotCount] = 0x21 and Set*Animation's Verify bounds against that instead. Sizing a real array off a name table that stops earlier reads fine and corrupts whatever sits next door; caught by reading the clip loader, not by the compiler. THE SLOT MAP, recovered from LoadLocomotionClips and now written down in full (suffix, meaning, and which measured constant each clip yields): 5 swr stand -> walk standSpeed 6/7 wwr/wwl forward walk CYCLE walkStrideLength = (s6+s7)/(d6+d7) 8/9 wsr/wsl walk -> stand 10/11 wrr/wrl walk -> run reverseSpeedMax 12/13 rrr/rrl run CYCLE reverseStrideLength 14/15 rwr/rwl run -> walk 16/17 sbr/sbl stand -> back gimpSpeedMax 18/19 bbr/bbl reverse CYCLE gimpStrideLength (NEGATED here) 20/21 bsr/bsl back -> stand 22/23 wgl/wgr walk -> limp gimpLeft/RightSpeedMax 24/25 ggr/ggl limp CYCLE gimpLeft/RightStrideLength 26/27 gsl/gsr limp -> stand 0x20 bmp bump / crash stagger THE TRAP: THE "gimp*" MEMBERS ARE THE REVERSE FIGURES, NOT THE LIMP ONES. gimpSpeedMax and gimpStrideLength are measured from sbr and bbr/bbl -- the reverse gait. The real limp has its own gimpLeft*/gimpRight* pair. This is the same bad naming that produced the states-16-19 misreading recorded in 5.3.91, and it has now caused the same error twice from two directions. Also settled: gimpStrideLength's negative sign is applied AT MEASUREMENT, not authored into the data -- which is where the fold in the transition machines comes from. And the limp clips are OPTIONAL: the loader probes for wgl and leaves hasGimpClips 0 with slots 22-27 unfilled if the model lacks it, so the deferred gimp branch must check that before routing into the limp machine. THE ENUM IS NOT THE SLOT MAP, and MECH.HPP now says so at the enum itself. The names are verbatim from the binary and authoritative AS NAMES, but slot 0x0e takes the run-to-walk clip while the table calls it RightReverseAnimation, and the forward walk alternates 6/7 rather than the pair the WalkForward names suggest. Read the slot map for "what does this play"; read the enum for "what did the original call this index". ATTRIBUTION NOTE: the four clip helpers (ResolveAnimationClip @004a7f50, MeasureClipStride @004a8054, LoadLocomotionClips @004a80d4, LoadLocomotionClipsExt @004a86c8) are exactly the four addresses the manifest lists under mech2.cpp that BT411 files under mech3. The manifest's attribution comes from the binary's own file tagging, so they belong here -- which also accounts for all 12 of mech2's functions. BT 51/51. Still nothing calls the gait.

Scene Restorations
Modern re-renderings of the Division dVS scenes recovered from the Glaze developer drive (see HISTORY.md) and this repo's CONTENT tree. The originals ran on Division Ltd.'s pixel-pipeline hardware in 1994–1997; these tools parse the original data files and re-render them in WebGL, in the browser.
Viewers (open in any browser, fully self-contained)
vwe-archive.html— the Scene Archive: 26 curated scenes across all projects — Star Trek (Enterprise-D, Klingon flyby), Hull Pressure (sea demos, fish schools, sunken temple), BattleTech (polar map with mech lineup, Ravine and desert maps, stadium), Red Planet (Blade arena, the Mars canal milestone demo), and the Canyon/Maya-temple Division demos. Fly camera: drag to look, WASD to fly, R resets.trek-scn.html— the original standalone Star Trek restoration (TREK.SCN and KLNGVID.SCN).
Toolkit
divformats.py— parsers for every Division format found on the drive: textVGF/VMF(DIV-VIZ2 geometry/materials, both the 1995VERSION 2:07and 199602:05dialects, with header SCALE support), binaryBGF/BMF(DIV-BIZ2) — the binary block-stream layout was recovered from Division's own reader source (DPL3/BIZREAD.C, 1994), including all 14 vertex layouts, pmesh/tristrip/polygon connectivity, LOD blocks (newer writers nest patches inside LODs; the largest LOD is taken), and embedded materials/textures/ramps — plusTGAand rawSVTtextures,SPLsplines, andSCNscene scripts.audit.py— scans every.SCNon the drive and reports what fraction of its geometry survives, and in which format.extract_all.py— extracts every scene with ≥60 % of its geometry recoverable (108 of 241 on the drive; the rest reference lost models) intoallscenes.json, resolving models/materials/textures across the drive and this repo's CONTENT dirs.gallery_build.py— curates scenes fromallscenes.jsoninto the self-containedvwe-archive.html(viagallery_template.html).convert.py/viewer_template.html— the original single-scene Star Trek pipeline.

Fidelity notes
Faithful: vertices, triangles, material colors and shading ramps, textures,
fog and light parameters, spline motion, camera start positions. Approximated:
Division's rasterizer behavior, point sizes, timing (originals ran at 30 Hz).
Not simulated: event-driven SPECIALFX particles. A few dev scenes had camera
start positions inside geometry; those get overridden or auto-framed cameras
(see START_OVERRIDE in gallery_build.py). Scenes missing one or more
models from the drive say so in their header.
