# Weapon and first-person hand credits

## AK-74m weapon — creationwasteland; animation/adaptation by Cransh

`carbine.glb` is the weapon-only derivative of **FPS AK-74m Animations** by **Cransh**, whose published description credits **creationwasteland** for the AK model.

- Original credited model creator profile: https://sketchfab.com/creationwasteland . This profile was unavailable when checked; the original leaf model's license could not be independently recovered. The retained weapon relies on Cransh's explicit CC BY publication and embedded attribution, not an assertion that the original leaf license was independently verified.

The adaptation also contained older DJMaesen first-person arms whose separate original listing is **CC BY-NC**: https://sketchfab.com/3d-models/fp-arms-8416c380544949bb9b224278819cbe6b . **Those arm meshes, texture images, and arm animation channels are excluded from this runtime derivative.** Shared source buffers were repacked by retained accessors, so excluded hand geometry is not merely hidden inside the file. Unused transform nodes remain to preserve weapon hierarchy; they contain no hand geometry or textures. The combined original stays in development source storage only and must not be copied into public assets.

Runtime changes: two weapon skinned meshes retained (main rifle and reload magazine), 25,171 triangles; weapon mechanical tracks retained from the eight original actions; main receiver motion stabilized at runtime; glTF repacked into GLB; three 2048px maps converted to JPEG; redundant specular map removed while retaining metallic/roughness material workflow; viewmodel and enemy scale/orientation normalized. Separate clean hands are described below. Firing, ammo, hit processing, and gameplay timing are Winterline implementation.

## Eric Rigged 001 hands and forearms — Renderpeople

`hands.glb` contains only selected forearm/hand triangles from **Eric Rigged 001** by **Renderpeople**.

Runtime changes: geometry extracted by forearm/hand skin weights (original extraction: 2,006 vertices and 3,458 triangles; current gloves: 7,464 vertices and 13,832 triangles after one welded Loop subdivision with interpolated normalized weights and smooth normals); excluded upper-arm influences removed and weights renormalized; forearm twist influences remapped to posed forearms; rear sleeves extended to keep the extraction edge outside the view; original diffuse/normal maps retained, gloss converted to roughness; source body/head geometry omitted; no imported locomotion animations retained in this hand asset. Skin and cloth triangles retain two material groups. Original maps remain in the asset; runtime shaders replace the hand albedo and normal detail with fitted charcoal gloves, leather palms, fabric backs and stitched seams. Sleeves retain the scanned cloth map with a charcoal tint. Forearm roll follows the hand, elbows track camera-relative body anchors, fingers flex toward each palm with constrained thumb hinges, and reload hand paths are driven by Winterline code. Rear sleeve coverage is fitted to hide the extraction boundary through the inspected weapon poses. The creator's separately published CC BY grant is recorded above; do not market the original website sample pack as a standalone asset product.

## Springfield Armory XD Mod.2 pistol - raimeiyonke; animation - Cransh

`pistol.glb` supplies the detailed Morrow 9 weapon. The original weapon creator is **raimeiyonke**. The separate slide and magazine animation was published by **Cransh**.

The mirror lost embedded creator attribution. Identity was checked against the named XD meshes, Springfield/XD/GRIPZONE textures, and the animation creator's explicit credit to the linked original weapon. This provenance-chain limitation is retained here. The adaptation also contained the older DJMaesen NC arms described above. All arm meshes, images, animation tracks, skins, and unused nodes were removed by repacking only the retained weapon data. The combined original is development-only. No game code from the mirror was copied.

Runtime modifications: retained three compact weapon skins (frame, slide, magazine), 17,818 triangles, and weapon mechanical tracks; removed arm/camera motion; normalized metric orientation and stabilized the receiver; converted legacy specular/glossiness material to metallic/roughness using the published Khronos conversion; packaged 1K base-color/normal JPEG and lossless metallic/roughness PNG textures. Conversion decodes color maps to linear light, derives metallic and base color from diffuse/specular values, and writes roughness as one minus glossiness. Winterline supplies firing timing, grip posing, recoil and reload choreography. The pistol magazine and supporting hand follow a shared continuous reload path; the reused magazine is exchanged below the view rather than producing a persistent dropped magazine. Runtime file approximately 3.806 MB.

## Remington 870 Police Magnum - 8sianDude / haoliu95

`shotgun.glb` supplies the detailed Lockwood 12. Complete creator attribution, CC BY 4.0 source links, acquisition limitations and geometry/animation changes are in [SHOTGUN-LICENSE.md](SHOTGUN-LICENSE.md). Winterline additionally reuses the source loose shell for visible per-shell loading. All three weapons share the clean Renderpeople hands documented above. These adaptations remain subject to visual and gameplay development; third-party asset use is not a claim of finished AAA quality.

# OLLY OLLY additions

Copied from WINTERLINE with their credits above; every image was re-encoded at 1024 px or less (`tools/blender/gun_glb_1k.py`); geometry, skins and animation are unchanged.

## Hunting rifle - Poly Haven, CC0

`rifle.glb` is **Bolt Action Rifle 7.62** from Poly Haven (https://polyhaven.com/a/bolt_action_rifle_7_62), released under **CC0 1.0** (https://creativecommons.org/publicdomain/zero/1.0/). Made into a viewmodel part by `tools/blender/gun_rifle.py`: the scope removed, turned to point -Z, the origin moved onto the bore over the magazine, the bolt handle and bolt joined into one part with its own axis, the loose round and the trigger kept as parts, textures re-encoded at 1K. Credit is not required; it is given anyway.

## The kick's boot and trouser leg - made here

`boot.glb` is modelled by `tools/blender/gun_boot.py` for this game. Its textures are **Leather014** and **Fabric001** by ambientCG (https://ambientcg.com), **CC0 1.0**, re-encoded at 512 px.

## The range

`range/*.glb` are Poly Haven models under **CC0 1.0**: Wooden Crate 02, Cardboard Box 01, Street Lamp 01, Barrel 01, Wooden Picnic Table, Lantern 01 (https://polyhaven.com/models), packed into GLBs with 1K images by `tools/blender/gun_pack.py`. `range/ground.*` and `range/gravel.*` are ambientCG **Ground048** and **Gravel022** (CC0 1.0) encoded by `tools/textures/encode.py`.
