blender-export: Workflow Automation for AI Agents | OpenAgentSkill

Overview

Export Blender scenes to glTF/GLB (web/AR), FBX (game engines), OBJ (universal), USD (VFX pipelines), STL (3D printing). Includes per-format settings, embed/unpack textures, axis conversion, polygon optimization (Decimate), and target-platform validation. Use whenever the user asks to "export this", "save as glTF / FBX / OBJ / STL / USD", "package for Unity / Unreal / Three.js / web / AR / 3D print", or any output format conversion. Make sure to use this skill even if the user does not say "export" — also covers "package this for the web", "make it work in Unity", "send to Unreal", "save for 3D printing".

Blender Export

Export to the right format with the right settings. Wrong format choice = days of debugging in the target platform.

Format decision tree

Where is this going?
├── Web (Three.js, Babylon.js, model-viewer, AR Quick Look) → glTF / GLB
├── Game engine (Unity, Unreal, Godot)
│   ├── Animated/rigged → FBX (or glTF for modern engines)

Quick rule for unknown target: glTF / GLB. Open standard, modern, universally supported.

Recipes

Recipe 1 — glTF / GLB export (web / AR / general)

import bpy

bpy.ops.export_scene.gltf(
    filepath='/tmp/output.glb',
    export_format='GLB',                 # single-file binary; preferred
    export_apply=True,                   # apply modifiers before export
    export_materials='EXPORT',
    export_image_format='AUTO',          # PNG; AUTO falls back to JPEG for opaque images
    export_yup=True,                     # Y-up convention (most engines / web expect this)
    export_animations=True,              # toggle off for static models
    export_morph=True,                   # shape keys
    export_skins=True,                   # armatures + weights
    export_normals=True,
    export_tangents=False,               # skip unless target uses tangent-space normals beyond standard
)

# Verify
import os
size_mb = os.path.getsize('/tmp/output.glb') / (1024 * 1024)
print(f"export:gltf {size_mb:.2f} MB")

glTF caveats:

Only Principled BSDF materials export cleanly. Procedural shaders are dropped or simplified.
Hard cap: 15 MB; soft target: 8 MB.
No KTX2 / Draco compression (unless target supports those loaders).
PNG textures only (max 1024×1024 typical).

Recipe 2 — Decimate before export (if too large)

import bpy

obj = bpy.data.objects['GEO-target']
bpy.context.view_layer.objects.active = obj

mod = obj.modifiers.new('Decimate', type='DECIMATE')
mod.ratio = 0.7    # keep 70% of faces; lower = more reduction
mod.use_collapse_degenerate = True
bpy.ops.object.modifier_apply(modifier=mod.name)

print(f"decimated:{obj.name} verts:{len(obj.data.vertices)}")

Then re-export. Iterate ratio until file size fits target.

Recipe 3 — FBX export (game engines)

import bpy

bpy.ops.export_scene.fbx(
    filepath='/tmp/output.fbx',
    use_selection=False,
    apply_unit_scale=True,
    apply_scale_options='FBX_SCALE_ALL',
    bake_space_transform=True,        # critical: applies rotation to mesh
    object_types={'MESH', 'ARMATURE', 'EMPTY'},
    use_mesh_modifiers=True,
    mesh_smooth_type='FACE',
    use_armature_deform_only=True,
    bake_anim=True,
    bake_anim_use_all_bones=True,
    bake_anim_use_nla_strips=True,
    bake_anim_use_all_actions=True,
    bake_anim_force_startend_keying=True,
    embed_textures=True,              # critical: embed textures into FBX
    path_mode='COPY',
    axis_forward='-Z',
    axis_up='Y',
)
print('export:fbx')

Common FBX gotchas:

Model rotated 90° in target → check axis_up='Y', axis_forward='-Z'
Model 100× too large → Apply Transform on the object before export
Textures missing → embed_textures=True, path_mode='COPY'
Animation only plays one action → use NLA + bake all actions

Recipe 4 — OBJ export (simple / universal)

import bpy

bpy.ops.wm.obj_export(
    filepath='/tmp/output.obj',
    export_animation=False,
    apply_modifiers=True,
    export_eval_mode='DAG_EVAL_VIEWPORT',
    export_uv=True,
    export_normals=True,
    export_materials=True,
    export_triangulated_mesh=False,
    forward_axis='NEGATIVE_Z',
    up_axis='Y',
)
print('export:obj')

OBJ has no animation, no rigging, basic material support only. Use for simple geometry exchange.

Recipe 5 — STL export (3D printing)

import bpy

bpy.ops.wm.stl_export(
    filepath='/tmp/output.stl',
    ascii_format=False,    # binary STL (smaller, faster)
    apply_modifiers=True,
)
print('export:stl')

Critical for STL:

Mesh must be watertight (no holes, no flipped normals, no internal faces).
Pre-export: in Edit Mode, run Mesh → Clean Up → Make Manifold.
STL has NO units — most slicers assume mm. Set Blender scene units to mm before modeling.
STL has NO color/material — single-color grey only.

Recipe 6 — USD export (VFX pipeline)

import bpy

bpy.ops.wm.usd_export(
    filepath='/tmp/scene.usdc',
    export_animation=True,
    export_uvmaps=True,
    export_normals=True,
    export_materials=True,
    use_instancing=True,
    export_textures=True,
    overwrite_textures=True,
)
print('export:usd')

USD variants:

.usd — text-based (debuggable, large)
.usdc — binary (compact, fast — default choice)
.usda — ASCII (human-readable, larger)
.usdz — zipped USD with all assets (Apple AR / iOS)

Recipe 7 — Pre-export checklist (run before any export)

import bpy

# 1. Apply transforms (rotation + scale baked into geometry)
obj = bpy.data.objects['GEO-target']
bpy.context.view_layer.objects.active = obj
bpy.ops.object.transform_apply(location=False, rotation=True, scale=True)

# 2. Recompute normals
bpy.ops.object.mode_set(mode='EDIT')
bpy.ops.mesh.select_all(action='SELECT')
bpy.ops.mesh.normals_make_consistent(inside=False)
bpy.ops.mesh.remove_doubles(threshold=0.0001)
bpy.ops.object.mode_set(mode='OBJECT')

# 3. Apply modifiers (some exporters keep them, but for portability apply before export)
# Already done via export_apply=True / use_mesh_modifiers=True flags

# 4. Verify mesh stats
mesh = obj.data
print(f"export_check:{obj.name} verts:{len(mesh.vertices)} faces:{len(mesh.polygons)}")

Recipe 8 — Verify exported file

import os

filepath = '/tmp/output.glb'
if not os.path.exists(filepath):
    print(f"ERROR:not_found {filepath}")
else:
    size_mb = os.path.getsize(filepath) / (1024 * 1024)
    print(f"verified:{filepath} {size_mb:.2f}MB")

Always verify after export. Use Bash tool: ls -la /tmp/output.glb.

Polycount targets per platform

Platform	Target	Notes
Web (glTF)	≤ 30 000 tris	Mobile-safe
Hero web asset	≤ 60 000 tris	Desktop OK
Unity / Unreal hero	50 000–100 000 tris	High-end
Mobile game	≤ 10 000 tris	Per asset
AR USDZ	≤ 50 000 tris	iOS recommendation
3D print	unlimited	But export size matters

Common pitfalls

Symptom	Fix
FBX has no textures	Set `embed_textures=True, path_mode='COPY'`
Procedural material missing in glTF	Bake to image textures first; use only Principled BSDF
Game engine: model rotated 90°	FBX: `axis_up='Y', axis_forward='-Z'`; glTF: `export_yup=True`
Game engine: model 100× too large	Apply Transform; check unit scale
OBJ won't import elsewhere	Stick to ASCII filenames
STL won't print	Make Manifold; recompute normals
GLB > 15 MB	Apply Decimate (Recipe 2); reduce textures to 1024×1024
Bone count exceeded	Limit weights to 4 per vertex; reduce bone count
Animation didn't export	glTF: `export_animations=True`; FBX: `bake_anim=True`

**Quick rule for unknown target**: glTF / GLB. Open standard, modern, universally supported.

## Recipes

### Recipe 1 — glTF / GLB export (web / AR / general)

```python
import bpy

bpy.ops.export_scene.gltf(
    filepath='/tmp/output.glb',
    export_format='GLB',                 # single-file binary; preferred
    export_apply=True,                   # apply modifiers before export
    export_materials='EXPORT',
    export_image_format='AUTO',          # PNG; AUTO falls back to JPEG for opaque images
    export_yup=True,                     # Y-up convention (most engines / web expect this)
    export_animations=True,              # toggle off for static models
    export_morph=True,                   # shape keys
    export_skins=True,                   # armatures + weights
    export_normals=True,
    export_tangents=False,               # skip unless target uses tangent-space normals beyond standard
)

# Verify
import os
size_mb = os.path.getsize('/tmp/output.glb') / (1024 * 1024)
print(f"export:gltf {size_mb:.2f} MB")
```

**glTF caveats**:
- Only Principled BSDF materials export cleanly. Procedural shaders are dropped or simplified.
- Hard cap: 15 MB; soft target: 8 MB.
- No KTX2 / Draco compression (unless target supports those loaders).
- PNG textures only (max 1024×1024 typical).

### Recipe 2 — Decimate before export (if too large)

```python
import bpy

obj = bpy.data.objects['GEO-target']
bpy.context.view_layer.objects.active = obj

mod = obj.modifiers.new('Decimate', type='DECIMATE')
mod.ratio = 0.7    # keep 70% of faces; lower = more reduction
mod.use_collapse_degenerate = True
bpy.ops.object.modifier_apply(modifier=mod.name)

print(f"decimated:{obj.name} verts:{len(obj.data.vertices)}")
```

Then re-export. Iterate ratio until file size fits target.

### Recipe 3 — FBX export (game engines)

```python
import bpy

bpy.ops.export_scene.fbx(
    filepath='/tmp/output.fbx',
    use_selection=False,
    apply_unit_scale=True,
    apply_scale_options='FBX_SCALE_ALL',
    bake_space_transform=True,        # critical: applies rotation to mesh
    object_types={'MESH', 'ARMATURE', 'EMPTY'},
    use_mesh_modifiers=True,
    mesh_smooth_type='FACE',
    use_armature_deform_only=True,
    bake_anim=True,
    bake_anim_use_all_bones=True,
    bake_anim_use_nla_strips=True,
    bake_anim_use_all_actions=True,
    bake_anim_force_startend_keying=True,
    embed_textures=True,              # critical: embed textures into FBX
    path_mode='COPY',
    axis_forward='-Z',
    axis_up='Y',
)
print('export:fbx')
```

**Common FBX gotchas**:
- Model rotated 90° in target → check `axis_up='Y', axis_forward='-Z'`
- Model 100× too large → Apply Transform on the object before export
- Textures missing → `embed_textures=True, path_mode='COPY'`
- Animation only plays one action → use NLA + bake all actions

### Recipe 4 — OBJ export (simple / universal)

```python
import bpy

bpy.ops.wm.obj_export(
    filepath='/tmp/output.obj',
    export_animation=False,
    apply_modifiers=True,
    export_eval_mode='DAG_EVAL_VIEWPORT',
    export_uv=True,
    export_normals=True,
    export_materials=True,
    export_triangulated_mesh=False,
    forward_axis='NEGATIVE_Z',
    up_axis='Y',
)
print('export:obj')
```

OBJ has no animation, no rigging, basic material support only. Use for simple geometry exchange.

### Recipe 5 — STL export (3D printing)

```python
import bpy

bpy.ops.wm.stl_export(
    filepath='/tmp/output.stl',
    ascii_format=False,    # binary STL (smaller, faster)
    apply_modifiers=True,
)
print('export:stl')
```

**Critical for STL**:
- Mesh must be **watertight** (no holes, no flipped normals, no internal faces).
- Pre-export: in Edit Mode, run `Mesh → Clean Up → Make Manifold`.
- STL has NO units — most slicers assume mm. Set Blender scene units to mm before modeling.
- STL has NO color/material — single-color grey only.

### Recipe 6 — USD export (VFX pipeline)

```python
import bpy

bpy.ops.wm.usd_export(
    filepath='/tmp/scene.usdc',
    export_animation=True,
    export_uvmaps=True,
    export_normals=True,
    export_materials=True,
    use_instancing=True,
    export_textures=True,
    overwrite_textures=True,
)
print('export:usd')
```

USD variants:
- `.usd` — text-based (debuggable, large)
- `.usdc` — binary (compact, fast — **default choice**)
- `.usda` — ASCII (human-readable, larger)
- `.usdz` — zipped USD with all assets (Apple AR / iOS)

### Recipe 7 — Pre-export checklist (run before any export)

```python
import bpy

# 1. Apply transforms (rotation + scale baked into geometry)
obj = bpy.data.objects['GEO-target']
bpy.context.view_layer.objects.active = obj
bpy.ops.object.transform_apply(location=False, rotation=True, scale=True)

# 2. Recompute normals
bpy.ops.object.mode_set(mode='EDIT')
bpy.ops.mesh.select_all(action='SELECT')
bpy.ops.mesh.normals_make_consistent(inside=False)
bpy.ops.mesh.remove_doubles(threshold=0.0001)
bpy.ops.object.mode_set(mode='OBJECT')

# 3. Apply modifiers (some exporters keep them, but for portability apply before export)
# Already done via export_apply=True / use_mesh_modifiers=True flags

# 4. Verify mesh stats
mesh = obj.data
print(f"export_check:{obj.name} verts:{len(mesh.vertices)} faces:{len(mesh.polygons)}")
```

### Recipe 8 — Verify exported file

```python
import os

filepath = '/tmp/output.glb'
if not os.path.exists(filepath):
    print(f"ERROR:not_found {filepath}")
else:
    size_mb = os.path.getsize(filepath) / (1024 * 1024)
    print(f"verified:{filepath} {size_mb:.2f}MB")
```

Always verify after export. Use `Bash` tool: `ls -la /tmp/output.glb`.

## Polycount targets per platform

| Platform | Target | Notes |
|----------|--------|-------|
| Web (glTF) | ≤ 30 000 tris | Mobile-safe |
| Hero web asset | ≤ 60 000 tris | Desktop OK |
| Unity / Unreal hero | 50 000–100 000 tris | High-end |
| Mobile game | ≤ 10 000 tris | Per asset |
| AR USDZ | ≤ 50 000 tris | iOS recommendation |
| 3D print | unlimited | But export size matters |

## Common pitfalls

| Symptom | Fix |
|---------|-----|
| FBX has no textures | Set `embed_textures=True, path_mode='COPY'` |
| Procedural material missing in glTF | Bake to image textures first; use only Principled BSDF |
| Game engine: model rotated 90° | FBX: `axis_up='Y', axis_forward='-Z'`; glTF: `export_yup=True` |
| Game engine: model 100× too large | Apply Transform; check unit scale |
| OBJ won't import elsewhere | Stick to ASCII filenames |
| STL won't print | Make Manifold; recompute normals |
| GLB > 15 MB | Apply Decimate (Recipe 2); reduce textures to 1024×1024 |
| Bone count exceeded | Limit weights to 4 per vertex; reduce bone count |
| Animation didn't export | glTF: `export_animations=True`; FBX: `bake_anim=True` |
