Included Files

All files were verified by direct file parsing.

Formats

BLEND

butcher.blend uses the Blender 4.0 file format (BLENDER-v400) and contains:

• 69 mesh datablocks

• 16 character/prop meshes

• 53 Auto-Rig Pro widget shapes

• 1 armature

• 739 bones

• 17 materials

• 26 image datablocks

No chainsaw object, Actions, or shape-key datablocks are present.

FBX

stylized butcher.fbx is FBX binary 7.4.

Verified:

• Skinned/deformer data

• 2,248 LimbNode occurrences

• Chainsaw01

• 1 AnimStack

• 0 AnimCurve occurrences

The single AnimStack has no baked animation.

FBX Video/Content/Media nodes are present. The file size is close to the texture package size, suggesting textures may be embedded, but this was not byte-for-byte confirmed.

OBJ + MTL

The OBJ contains:

• 61,752 vertices

• 67,637 UV coordinates

• 63,431 normals

• 61,078 faces

• 16 named objects

• Chainsaw01

OBJ does not support rigs or skinning.

Its higher vertex count compared with the .blend is a normal result of OBJ splitting vertices at UV/normal seams.

The MTL header identifies Blender 4.5.5 LTS.

GLB

The GLB contains:

• 814 nodes

• 19 meshes

• 15 materials

• 1 skin

• 23 embedded PNG images

• 0 animations

• Chainsaw geometry

Generator: Khronos glTF Blender I/O v4.5.49.

The belt Metallic and Roughness maps are combined for glTF. Two HG_Rig_body_* maps are not included, resulting in 23 embedded images.

Materials

The .blend contains 17 materials:

• body

• face and hand

• face with mustash

• hair

• shirt

• butcher coat

• belt

• trouser

• bunyan

• eyes / Material

• teeth/tongue / .HG_Teeth

• Material.001–Material.004 for the chainsaw

• cs_solid_red

• cs_blend_red

• Dots Stroke

cs_solid_red, cs_blend_red, and Dots Stroke are used for Auto-Rig Pro display widgets rather than character geometry.

face with mustash is defined in the .blend and OBJ/MTL but is not assigned to exported OBJ faces and is absent from the GLB material list.

All materials were identified as node-based except cs_blend_red and Dots Stroke. Individual shader node links were not decoded.

Textures

textures.zip contains 26 PNG files.

Body and Clothing

The following sets contain 1024 × 1024 Base Color and OpenGL Normal maps:

• Body

• Face and hand

• Hair

• Shirt

• Butcher coat

• Trouser

• Bunyan/boots

The belt also includes:

• Base Color — 1024²

• Normal — 1024²

• Roughness — 1024²

• Metallic — 1024²

Eyes:

• Base Color — 1024²

Teeth and Tongue

• TeethTongueSet_C_2K.png — 2048² Base Color

• TeethTongueSet_N_2K.png — 2048² Normal

Chainsaw

• Chainsaw01_DIFF.tga.png — 2048² Diffuse

• Chainsaw01_Chain.tga.png — 512 × 256 Diffuse/Mask

Additional Maps

• boyB_cloth_Color.1004.png — 4096² Base Color; not matched to a specific MTL slot.

• HG_Rig_body_Normal_normal.png — 4096² Normal.

• HG_Rig_body_Roughness_roughness.png — 4096² Roughness.

The HG_Rig_body_* maps belong to the unused face with mustash material.

The .1004 filename has no matching UDIM tiles, so it functions as a single texture.

PNG color-space settings were not independently verified.

Rig & Bones

The armature object is named:

Stylized Butcher Character Fully Rigged

It contains 739 verified bones using an Auto-Rig Pro control-rig structure.

Verified name-pattern groups:

• 319 .l

• 319 .r

• 99 .x

• 291 facial-related

• 124 finger/hand-related

• 13 spine-related

• 18 toe-related

• 196 _ref helper/reference bones

These are name-pattern counts rather than Auto-Rig Pro internal category definitions.

The hierarchy includes root/pelvis controls and IK/FK chains such as:

• c_pos

• c_traj

• c_root_master.x

• c_root.x

• root.x

• leg_ik.l

• leg_fk.l

• thigh_ik.l

• thigh_fk.l

The exact Auto-Rig Pro preset was not confirmed.

Animation

No animation data is included.

Verified:

• .blend: 0 Actions

• FBX: 1 AnimStack / 0 AnimCurves

• GLB: 0 animations

The character is supplied as a posable rig, not a pre-animated asset.

Shape Keys / Blendshapes

No shape keys or blendshapes exist.

The .blend contains zero Key datablocks and the inspected mesh shape-key links are null.

Facial customization is therefore bone-based.

UV

Every character/prop mesh has exactly one UV map.

Most use UVMap.

Exceptions:

• NurbsPath_004 — DiffuseUV

• NurbsPath_007 — DiffuseUV

• One teeth mesh — map1

No mesh contains multiple UV layers, and no complete UDIM tile set was found.

Geometry

The 16 non-widget mesh datablocks contain:

• 32,734 vertices

• 32,093 polygons

• 63,179 triangles

Auto-Rig Pro widget meshes are excluded.

Plane is an edge-only object.

No LOD variants or Geometry Nodes modifiers were found on the inspected meshes.

Dimensions & Scale

Verified scene settings:

• Unit system: Metric

• Unit scale: 1.0

• 1 Blender unit = 1 metre

A true world-space bounding-box size and per-object applied transforms were not calculated.

Object Structure & Collections

butcher.blend contains:

• 70 objects

• 69 Mesh objects

• 1 Armature

Of the Mesh objects:

• 16 are character/prop geometry

• 53 are Auto-Rig Pro cs_ display widgets

No Camera, Light, or Empty objects were found.

The file contains 1 Collection datablock. Its detailed member hierarchy was not individually decoded.

Modifiers, Constraints & Drivers

Exact modifier stacks were not decoded field-by-field.

The FBX and GLB confirm skin/deform relationships, but individual Blender modifier types, order, and settings were not verified.

Constraints and drivers were also not individually decoded. The IK/FK structure is supported by the verified bone naming, but individual constraint/driver records should not be assumed beyond that evidence.

Scene Setup

No Camera or Light objects are included.

The supplied renders were created using a separate render/lighting setup that is not part of the delivered .blend.

File Dependencies

Image datablock paths inside the .blend were not resolved to disk paths during inspection.

For the OBJ:

• Most texture references use a textures/ folder.

• map_Bump normal-map references use bare filenames.

If an OBJ importer does not resolve those references automatically, place the normal-map PNGs beside the OBJ/MTL as well.

Software / Version

• .blend: Blender 4.0 format

• .mtl: Blender 4.5.5 LTS

• .glb: Khronos glTF Blender I/O v4.5.49

• FBX: binary 7.4

File timestamps:

• butcher.blend: 2026-06-29

• FBX, GLB, OBJ, MTL, textures.zip: 2026-09-12

No live application testing was performed.

Customization

Available customization includes:

• Editing the 17 materials

• Replacing/repainting the 26 PNG textures

• Posing through the 739-bone rig

• Bone-based facial posing

• Using the exported chainsaw as a separate object

There are no blendshapes or supplied animations.

Rig Workflow

1. Open butcher.blend.

2. Select Stylized Butcher Character Fully Rigged.

3. Enter Pose Mode.

4. Use the c_ control bones for posing.

5. Use the IK/FK controls where available.

6. Use the facial controls for jaw, eyelids, lips, cheeks, and related facial posing.

The c_ controls are intended for user-facing rig manipulation; internal deform/reference bones should generally not be used for normal posing.

Import & Texture Workflow

Blender

1. Open butcher.blend in Blender 4.0 or newer.

2. Extract textures.zip.

3. Use File → External Data → Find Missing Files if textures are missing.

4. Select the armature to pose the character.

FBX

Import stylized butcher.fbx.

It contains skin/deformer data and the Chainsaw01 export.

No animation needs to be imported because no baked animation exists.

Texture embedding is suggested by the file structure but was not confirmed byte-for-byte.

OBJ

Keep stylized butcher.obj and .mtl together.

OBJ provides static mesh/material data only.

Check the normal-map path issue described under File Dependencies.

GLB

Import stylized butcher.glb as a self-contained glTF file.

Its 23 PNG images are embedded, so no external texture files are required for those images.

Material Workflow

1. Select the required object in Blender.

2. Open the Shading workspace.

3. Select its material.

4. Verify the corresponding image paths.

5. Replace or edit the required texture maps.

All 17 materials were identified as node-enabled except the two widget/stroke materials noted above. Their exact shader node connections were not deeply inspected.

Engine Workflow

FBX and GLB are the practical starting formats for rigged import because they contain skin/joint data.

OBJ is static mesh only.

The Auto-Rig Pro control rig is primarily a Blender authoring setup and contains many control/reference bones. Game-engine workflows may require baking or retargeting to a deform-bone subset.

Unity, Unreal Engine, and Godot were not tested.

Troubleshooting

Textures missing: Relink the extracted texture folder. For OBJ, check the bare-filename normal-map references.

Materials incorrect: Verify image paths first; the individual shader node structures were not deeply inspected.

Rig behaves incorrectly: Use the c_ control bones instead of directly manipulating internal deform/reference bones.

Animation missing: No animation data is supplied.

Scale incorrect: The source scene uses Metric units with a scale of 1.0. Check the target application's unit settings.

FBX problems: Ensure skeleton/deformer import is enabled.

OBJ problems: Keep OBJ/MTL together and check normal-map paths.

GLB texture problems: The 23 referenced images are embedded in the GLB.

Known Limitations

• The chainsaw is absent from butcher.blend and is available in the FBX, OBJ, and GLB exports.

• No animation data is supplied.

• No shape keys or blendshapes exist.

• No Camera or Light objects are included.

• The two render folders use slightly different filenames for one chainsaw side/clay-wireframe shot.

• face with mustash is effectively unused in the supplied exports.

• Exact modifier stacks, constraints, and drivers were not fully decoded.

• Real-world bounding-box dimensions were not calculated.

• Specific engine/application behavior was not tested.

Compatibility

Verified file formats:

• Blender 4.0-format .blend

• FBX 7.4

• glTF 2.0 GLB

• Wavefront OBJ/MTL

FBX and GLB contain skin/joint data and are suitable starting points for applications supporting those formats.

OBJ has no rig support.

Specific behavior in Unity, Unreal Engine, Godot, Maya, 3ds Max, Cinema 4D, or other applications was not tested.

Quick Start

1. Open butcher.blend in Blender 4.0 or newer.

2. Relink textures if required.

3. Select the armature and enter Pose Mode.

4. Pose with the c_ control bones.

5. Import the chainsaw from an export format if needed.

6. Add your own camera and lighting.

7. Export to FBX or GLB when required.

Important Notes

• The native .blend does not contain the chainsaw.

• The character is posable, not animated.

• There are no shape keys or blendshapes.

• The scene uses Metric units with a scale of 1.0.

• The package contains 17 materials and 26 PNG textures.

• The verified geometry totals apply to the 16 native non-widget meshes.

• File/application behavior outside the inspected file structures was not tested.
