Export Pipeline

Verified, engine-ready exports. Correct scale, axis, pivots, and data.

When to Use

• Final asset delivery
• Engine import preparation
• Animation/rig export
• Batch export of modular kits

Pre-Export Gate

Required: asset-optimization validation PASS before export.

Workflow

Validation PASS → Export Settings → Test Export → Engine Verify
    → Fix Issues → Final Export → Documentation

Format Selection

Format	Best For
FBX	Unreal, Unity (legacy), animation
GLTF/GLB	Web, Godot, modern Unity
OBJ	Static mesh interchange (no rig)
USD	Pipelines, VFX, multi-asset
Alembic	VFX caches, sculpt animation

FBX Settings (Game Default)

Scale: 1.0
Apply Scalings: FBX All
Forward: -Z Forward
Up: Y Up
Apply Unit: ON
Mesh: ON
Armature: ON (if rigged)
Bake Animation: ON (if animated)
Path Mode: Copy (embed textures)

GLTF Settings

Format: GLB (single file) or GLTF Separate
Include: Selected Objects
Transform: +Y Up
Compression: Draco (if supported by engine)

Export Verification Matrix

Check	Method
Scale	Measure known dimension in engine
Pivot	Verify floor contact / grip point
Forward axis	Compare to engine convention
Normals	Check shading in engine
Materials	Verify slot count and textures
Animation	Play action in engine
Collision	Import COL_ mesh separately

Engine-Specific Notes

Unreal Engine

• Scale 1.0 = 1cm in UE (confirm project; may need 0.01 export scale)
• Import normals and tangents
• Separate collision mesh import
• LOD naming for auto-LOD: SM_Asset_LOD0

Unity

• Scale 1.0 typically correct
• GLTF preferred for modern pipelines
• Humanoid rig mapping for characters

Godot

• GLTF/GLB preferred
• +Y up default
