AnimToFBXExporter

AnimToFBXExporter v1.1.5

Batch retarget Unity Humanoid animations and export clean FBX files for Blender, testing, cleanup, preview renders, or your wider 3D pipeline.

AnimToFBXExporter is a Unity Editor tool built for artists and game developers who need to turn Unity Humanoid AnimationClips into usable FBX exports without doing the same tedious setup one clip at a time.

Select your AnimationClips, assign a scene character, run a compatibility scan if needed, then export animation-only FBX files or full mesh + armature + animation FBX files in batches.

What It Does

Unity Humanoid animation is powerful inside Unity, but getting that animation back out into Blender or another DCC tool can be awkward. AnimToFBXExporter helps bridge that gap by sampling the retargeted Unity result and baking it into an export-friendly FBX workflow.

For mesh-bearing exports, the tool uses a staged pipeline: Unity samples the live retargeted character, bakes the animation onto a temporary Generic export hierarchy, exports model data from a clean source clone, then merges the baked animation back into the final FBX.

The goal is simple: fewer broken exports, fewer moving T-poses, fewer distorted meshes, and less manual cleanup.

Key Features

• Batch export selected Unity AnimationClip assets to FBX.
• Retarget Humanoid clips onto a selected scene character.
• Export animation-only FBX files or include mesh, armature, and animation.
• Optional root motion baking for export-ready movement.
• Humanoid bone position stabilization for stylized, chibi, or non-standard characters.
• Compatibility Scan to catch risky rig setups before exporting.
• Batch-safe exporting continues even if one clip fails.
• Duplicate-name protection for temporary assets and exported FBX files.
• Rest-pose scale preservation to reduce skinned mesh distortion.
• Warnings for common export risks like scaled parents, invalid Avatars, missing mesh data, and hierarchy issues.

Typical Workflow

1. Install Unity's official FBX Exporter package.
2. Add AnimToFBXExporterV1.1.5.cs to an Editor folder in your Unity project.
3. Open Tools > Batch Retarget & Export FBX (Store v1.1.5).
4. Select one or more AnimationClip assets in the Project window.
5. Drag your scene character root into the Target Model field.
6. Choose animation-only export or mesh + armature export.
7. Run Compatibility Scan if the rig is unfamiliar.
8. Click Export Selected Clips to FBX and choose an output folder.

Requirements

• Unity Editor project.
• Unity FBX Exporter package v5.0.0 or newer.
• Package name: com.unity.formats.fbx.
• For Humanoid clips, the target character needs a valid Humanoid Avatar.
• The target should be the scene root object that owns the Animator, not a child mesh or bone.

Best Results

For the cleanest mesh export, use a scene character that comes from an imported model asset such as an FBX. Keep the root scale clean, avoid scaled parents when possible, and run Compatibility Scan before exporting custom or unfamiliar rigs.

Animation-only export is usually the safest path. Mesh + armature export is more sensitive to bind poses, weighted bones, root bones, non-uniform scale, and unusual skeleton layouts.

Important Notes

AnimToFBXExporter is designed to improve Unity-to-FBX animation export workflows, especially for Humanoid retargeting, but no exporter can guarantee perfect results on every custom rig.

Extremely non-standard skeletons, missing bind pose data, null bone references, scaled parent hierarchies, or helper/deform bones outside Unity's Humanoid bone map may still require cleanup.

That is why Compatibility Scan is included: it helps you spot many common problems before committing to a full batch export.
