To Humble Bundle Users
If you had purchased the 'Humble Bundle', I'm afraid that you can't receive the regular upgrade.
To support the 'BLENDER_EEVEE_NEXT' render engine of Blender 4.2, please unzip 'better_fbx-5.4.18.zip', the contents should be in the directory of 'better_fbx-5.4.18'.
You may modify 'importer.py' and 'exporter.py' manually, replace all 'BLENDER_EEVEE' with 'BLENDER_EEVEE_NEXT'.
For your convenience, you can also download the two fixed files from: https://www.mesh-online.net/~test/fixed-files.zip, unzip the file, replace the original 'importer.py' and 'exporter.py' with the fixed 'importer.py' and 'exporter.py'.
Compress the directory of 'better_fbx-5.4.18' to 'better_fbx-5.4.18.zip' again.
Updated (July 31, 2024):
The support team had updated the humble bundle files, so you can simply re-download your humble bundle package to get 'better_fbx-5.4.19.zip'.
Who Don't Need It?
If Blender is your only toolchain, you don't need this add-on.
Who May Need It?
Game developers
Who need to import FBX files into Blender and export FBX files to game engines.
3d digital artists
Who need to share your 3d artworks to other 3d digital artists who use other 3d softwares, or you want to sell your 3d artworks in various digital markets.
What is it?
Blender is lack of native FBX support, when we import some older and newer FBX files, it often fails.
So I made a better FBX importer and exporter with official FBX SDK from scratch.
The add-on is compatible with all FBX versions, from ASCII to binary, from FBX 5.3 to FBX 2020.
I have tested the importer and exporter with about one hundred commercial FBX files which made by 3d digital artists in 3ds Max, Maya or Cinema 4D, the add-on can import and export these FBX files successfully.
The exported FBX and DAE files have been verified in Unity Engine 2021, Unreal Engine 4/5 and Godot Engine v4.1.1 with no issues.

Limitations
- Does not support IK bones*.
- Does not support custom bone shapes.
- Does not support multiple bind poses.
*IK Support
The add-on can export and import basic IK constraints since v4.1.10.
You can only use empty object as the target object, if you did not assign a target object, the add-on will create an empty object as the target object automatically.
The add-on can import basic IK constraints from Maya correctly, but the exported IK constraints are not compatible with Maya.
To import the basic IK constraints into Maya, you need to insert at least one keyframe of any object, for Maya treats IK constraints as animation data, if there isn't any animation data, the IK constraints will be ignored.
After imported the basic IK constraints into Maya, you will find that the bones can't be driven by the effector correctly, this is caused by the wrong pole vector value. To fix the issue, you need to copy the rotation value to the 'Pre-rotation' value for every bone between the IK chains, and reset the rotation value to zero, for Maya use the 'Pre-rotation' value to calculate the pole vector value.
As 3ds Max can't export and import IK constraints at all, you can't import and export IK constraints for 3ds Max.
Interface
Importer:
To import an FBX file, navigate to File->Import->Better FBX Importer (.fbx/.dae/.obj/.dxf/.3ds).
Then you can select leaf bone style, set scale value and other parameters, select the FBX file, click 'Better Import FBX' button to import the FBX file.
Exporter:
To export to an FBX file, navigate to File->Export->Better FBX Exporter (.fbx/.dae/.obj/.dxf).
Then you can select FBX version, set scale value and other parameters, enter a filename, click 'Better Export FBX' button to export to the FBX file.
Showcase
Here is an imported robot warrior in Cycles Renderer of Blender 2.79b, you may notice that his shield and weapon have already been attached to proper bones automatically, and all bones orientations have been corrected automatically, while the armature deform animation remains not changed.
Here is an imported ancient Chinese soldier in Eevee Renderer of Blender 2.80, you may notice that his spear has already been attached to the right-hand bone automatically, and all bones orientations have been corrected automatically, while the armature deform animation remains not changed.
Here are three characters in the Editor of Unity 2018, note that Santa's eyes, mouth and face are driven by shape key animation, and his body is driven by armature deform animation.
Here is one character in the Editor of Unreal Engine v4.22.3, the scene is the famous starter scene - 'Table, Glass And Chairs', note that Santa's eyes, mouth and face are driven by shape key animation, and his body is driven by armature deform animation.
Here is one character in the Editor of Godot Engine v3.2, the exported character(*.dae) and animation work properly.
Here is a simple cloth simulation in Blender 2.82, you can export the vertex animation as Maya(.mcx) format or 3ds Max(.pc2) format files; You can also import Maya(.mcx) format or 3ds Max(.pc2) format vertex animation files into Blender.

Cycles/Eevee Material
The add-on can import PBR materials from 3ds Max and Maya, including '3ds Max Physical Material', '3ds Max PBR (Metal/Rough) simplified PBR material', '3ds Max Arnold Standard Surface Material', 'Maya Arnold Standard Surface Material', and 'Maya StingRay PBS Material'.
The add-on can export PBR materials to 'FBX Standard Material', 'Unity Engine Compatible Material', and 'Unreal Engine Compatible Material'.
The add-on supports ten kinds of textures, including diffuse texture, reflection texture, specular texture, shininess texture, emissive texture, transparency texture, normal texture, bump texture, displacement texture, and ambient texture.
If you organize the texture image nodes according to the above picture, the add-on can export the texture images correctly.
Here are the details:
The first texture image is a diffuse texture, it can connect to the 'Basic Color' socket of the 'BSDF' node directly.
The second texture image is an ambient occlusion texture, you need to add an additional 'MixRGB' node to multiply the diffuse texture and the ambient occlusion texture, then connect the output of the 'MixRGB' node to the 'Basic Color' socket of the 'BSDF' node.
The third texture image is a metallic texture, it can connect to the 'Metallic' socket of the 'BSDF' node directly.
The fourth texture image is a specular texture, it can connect to the 'Specular' socket of the 'BSDF' node directly.
The fifth texture image is a roughness texture, it can connect to the 'Roughness' socket of the 'BSDF' node directly.
The sixth texture image is an emission texture, it can connect to the 'Emission' socket of the 'BSDF' node directly.
The seventh texture image is an alpha texture, it can connect to the 'Alpha' socket of the 'BSDF' node directly.
The eighth texture image is a normal texture, you need to add an additional 'Normal Map' node to configure the normal texture, then connect the output of the 'Normal Map' node to the 'Normal' socket of the 'BSDF' node.
The ninth texture image is a bump texture, you need to add an additional 'Bump' node to configure the bump texture, then connect the output of the 'bump' node to the 'Normal' socket of the 'BSDF' node.
The tenth texture image is a displacement texture, it can connect to the 'Displacement' socket of the 'Material Output' node directly, or you can also add an additional 'Displacement' node to configure the displacement texture, then connect the output of the 'Displacement' node to the 'Displacement' socket of the 'Material Output' node.
If you want to export other kind of textures, such as 'Clear Coat' texture, 'Anisotropic' texture, etc. you can add them to the shader editor, either isolated or connect to corresponding sockets of the 'BSDF' node is okay, you must enable the 'Embed Media' option when exporting, because they are not connected to any meshes in the FBX file, when importing into other 3d softwares or game engines, you need to load and setup them manually in their own material systems.
Material Style
There is a 'Material Style' option in the exporter since v4.4.2.
The default value is 'Blender', which means that the exported materials are compatible with Blender's material system and most other standard material systems.
You can export PBR materials for Unity Engine & Unreal Engine by changing material style.
If you change the option to 'Unity Engine', the add-on will export Unity Engine compatible materials, when you import the FBX file into the Unity editor, you'll find that all the texture channels have been setup correctly.
Here is the material in Unity editor:
Make sure that the 'Material Creation Mode' is 'Import via MaterialDescription', If you have embedded textures into the FBX file, please click the 'Extract Textures...' button to extract all embedded textures; Otherwise, please click the 'Extract Materials...' button to extract the material.
If you drag the FBX asset to the scene, an instance will be created, the 'Autodesk Interactive' shader is used, all the four channels will appear in the inspector panel automatically; If you want to use other shaders, you may need to assign some texture channels manually.
Unity Engine's importer will not import the ambient occlusion texture automatically, you need to import and assign the ambient occlusion texture manually.
If you change the option to 'Unreal Engine', the add-on will export Unreal Engine compatible materials, when you import the FBX file into the Unreal editor, you'll find that all the texture channels have been setup correctly.
Here is the material in Unreal editor:
Unreal Engine's importer will not import the ambient occlusion texture automatically, you need to import and assign the ambient occlusion texture manually.
Embed Media
The add-on supports exporting embedded texture images into FBX file since v4.3.0.
If you want to embed all texture images into the FBX file, enable 'Embed Media' when exporting, all texture images in the shader editors will be embedded into the FBX file.
If you want to export PBR materials, you can bake the PBR materials into texture images first, search 'bake' in the Blender Market, you can find some excellent baking tools, such as 'Bake Wrangler', 'Simplebake', 'Baketool', 'PBR Texture Bakery', etc. You can choose your favorite baking tool to bake, my favorite baking tool is https://github.com/meshonline/EasyPBRBake, it is not as powerful as commercial products, but the function is enough for me. Then add the baked texture images into shader editor.
When exporting, just enable 'Embed Media', all texture images in the shader editors will be embedded into the FBX file.
Though all texture images are embedded into the FBX file, only several kind of textures can be recognized when importing into other 3d softwares and game engines, you need to load and setup them manually in their own material systems.
Generic Rigging System
This add-on can export from any generic rigging system.
The exported armature is generic, is not retarget-able, because the bones hierarchy has not been configured for game engines, but the animations work properly in any game engines.
I have verified Rigify Auto-Rigging System and Auto-Rig Pro.
If you are Auto-Rig Pro user, please use its own FBX exporter, for its exported armature is retarget-able, while that exported from this add-on is not retarget-able.
The exported FBX files can be imported to Unity Engine 2019 and Unreal Engine 4/5, and the animations work properly.
When you have finished your character, just export with this add-on, no extra setup needed.
Rigify Auto-Rigging System
This add-on supports exporting game-friendly armature from Rigify Auto-Rigging System, including retarget-able humanoid armature, quadrupled armature, or any user-defined armatures.
I recommend the paid tutorials of Rig Anything With Rigify, which will teach you everything about Rigify Auto-Rigging System.
Retarget-able human armature means that Unity Engine 2019 and Unreal Engine 4/5 can recognize the human armature and map the bones hierarchy to game engine's inner bones hierarchy, you can retarget tons of animations to your armature in game engine.
When you have finished your character, just export it with this add-on.
Select the Rigify-Rig and the skinned character, from the export interface, enable the 'Selected Objects' option and the 'Rigify Armature' option, the add-on will export game-friendly character from Rigify Auto-Rigging System.
There is also an 'Only Selected Deform Bones' option, if you enable the option, the add-on will export only selected deform bones in 'EDIT' mode.
Generic Rigify Workflow
Video Package: Download the HD version of the video(Format:zip,Size:23MB,Date:Mar 18,2022).
Watch Online:
Here is a Character with Rigify Auto-Rigging System in Blender 2.79b, it does not contain any armature deform animations.
Here is the same character in Unity Engine 2018, Unity Engine recognized all bones.
Here is the same character in Unreal Engine 4, Unreal Engine recognized most bones, a few bones have been mapped to wrong bones, but it's not difficult to fix the wrong mappings.
For your convenience, here are the right mappings.
This is the complete Bone Mapping Preset, you can download and load the preset in the retarget manager to avoid fixing bone mapping manually.
Here is a zebra with Rigify Auto-Rigging System in Blender 3.1.0, I turned off IK and retargeted a walk cycle animation take to FK bones.
Here is the same zebra in Unity Engine 2020, I had exported the 3d model with v5.0.1.
Here is the same zebra in Unreal Engine 4, I had exported the 3d model with v5.0.1.
Here is the same zebra in Godot Engine 3.4, I had exported the 3d model as DAE with v5.0.1.
I have also tested some other 3d models, including all the weird creatures in Rig Anything With Rigify, all the exported 3d models can work very well in Unity Engine, Unreal Engine, and Godot Engine.
Optimize For Blender
The add-on can import Blender friendly armature and 3d models, the imported armature and 3d models have unit scale and zero rotations.
This is an experimental feature, which may has bugs, use the feature at your own risk.
Optimize For Game Engine
The add-on can export game engine friendly armature and 3d models, the exported armature and 3d models have unit scale and zero rotations.
This feature is very useful for game development, for animation retargeting usually requires that the armature has unit scale and zero rotations, and it is easy to manipulate 3d models via code if they have unit scale and zero rotations.
You can use Blender's default setting to work, use meter as the unit of the scene, and use 1.0 as the scale of the scene.
When exporting, make sure you have enabled the 'Optimize For Game Engine' option, the option is enabled by default.
Just export the contents, the exporter will convert meter to centimeter automatically, and apply all rotations to zero automatically.
I have verified in Unity Engine 2019.3.3f1, Unreal Engine v4.22.3, Godot Engine v3.2, all the armatures and 3d models have unit scale and zero rotations.
Godot Engine Support - New
Unity has invented 'Unity Runtime Fee' recently, many small teams are considering switching to Godot Engine to avoid the risk of potential bankruptcy.
So I downloaded and installed the latest Godot Editor v4.1.1, and exported the animated zebra 3d model bound by the Rigify Auto-Rigging System from within Blender 3.3 LTS.
Godot Editor v4.0 introduced the 'FBX2glTF' utility to detect and import FBX files. After I exported the FBX file to the resource directory, Godot Editor detected it immediately and started to import the FBX file, a few seconds later, the importing process completed.
Then I drag the FBX to the scene to test if the 3d model and the animation is correct, to my surprise, it worked without any issues!
I also tested other 3d models, from static meshes to skinned 3d characters, all of them worked without any issues!
In my test, the exported FBX files are 100% compatible with Godot Editor v4.1.1.
The add-on supports all the PBR channels in Godot Engine v4.1.1 since v5.4.0.
When exporting, you just need to setup the 'Material Style' to 'Godot Engine', then export the contents to FBX file, Godot Editor v4.1.1 will import all the PBR channels successfully.
Here is the screenshot, you can see that all the PBR channels were imported correctly:
If you are still using Godot Engine v3.x, I recommend the 'DAE' format, you can setup 'File Type' to 'DAE' and export a DAE file, then import the DAE file into Godot Engine v3.x.
Fix DAE File
It does three things:
It eliminates ncl's that get added to names.
It converts FBXASC strings back to their original characters.
It converts empty [/tag]'s, which chokes some viewers, to [tag][/tag] pairs.
You can download the BASH script from: https://www.mesh-online.net/~test/cleanCollada.sh
This commented BASH script is for Linux/Cygwin users by default, while it contains a hint on how to use it in Windows.
This BASH script is contributed by one of my customers, thanks for creating such a useful BASH script for us.
UDIM Mapping
Version 4.2.2 supports UDIM Mapping.
You can import UDIM mapping into Blender 2.82 or newer versions.
You can export UDIM mapping from Blender 2.82 or newer versions.
Zbrush Workflow
The add-on supports importing and exporting edge crease weights, you can transfer 3d models with edge crease weights lossless between Blender and Zbrush.
For example:
In blender side, you can setup a special pose for the armature deformed character to prepare to sculpt some details in Zbrush, you can click and select the charcter only, export the charcter with the add-on, from within the exporter panel, enable the 'Selected Objects' option, enable the 'Apply Modifiers' option, and enable the 'Include Armature Deform Modifier' option, then export the character to FBX file.
In Zbrush side, import the exported character, add some sculpture details, then export the detailed charcter to an ASCII format of FBX file, since Zbrush's FBX plugin has a bug for binary format of FBX, the add-on only supports ASCII format of FBX files exported from Zbrush with edge crease weights lossless until Zbrush fixed the bug.
Back to blender side, import the detailed charcter with the add-on, bind it back to its armature.
Special thanks to Tsukasa YAMATO, the famous Zbrush plugin creator from Japan, without his help, the Zbrush workflow will not be born.
Import Multiple Files
Since version 4.0, the add-on supports importing multiple files, you can simply select multiple files when importing, the importer will import them all into the current collection of the scene.
Version 5.4.20 supports importing multiple files to separate collections by filenames, if you want to import files to separate collections, you can enable the 'Separate Collection' option when importing.
Export Objects to Separate Files
Export objects to separate files by object names, if you want to export all objects to separate files, you can enable the 'Separate Files' option when exporting.
If you enable both the 'Separate Files' option and the 'Move To Origin' option, the add-on will move all objects to origin when exporting, and move them back automatically after exporting.
Export Collections to Separate Files
Version 5.4.20 supports exporting visible and non-empty collections to separate files by collection names, if you want to export collections to separate files, you can enable the 'Separate Collection' option when exporting.
You can also put all collection objects to a unique root empty node in each collection, if you enable both the 'Separate Collection' option and the 'Move To Origin' option, the add-on will move each unique root empty node to origin when exporting, and move each unique root empty node back after exporting, but each unique root empty node itself will not be exported.
In this way, you can move all collection objects to origin when exporting, while keeping hierarchy and relative transform not changed. If there is no unique root empty node found in the collection, all the collection objects will be moved to origin when exporting, and move them back automatically after exporting.
Export To Single File
I recommend that you design animations in 'NLA Editor', in this way, you store animations into virtual tracks, while don't touch the original keyframe actions.
By default, the add-on only exports the active animation, if you want to export separate animations, you need to change active animations one by one, every time you export an animation.
If you want to export the active animation in 'Action Editor' instead of the active animation in 'NLA Editor', you must delete all tracks in 'NLA Editor', for 'NLA Editor' has higher priority than 'Action Editor'.
You usually don't need to bake animation before exporting, just export when you are ready.
If you find that the exported animation is not as the same as it in Blender, try baking animation before exporting, for baking animation can always fix various issues.
Export Multiple Actions
I recommend that you design animations in 'NLA Editor', in this way, you store animations into virtual tracks, while don't touch the original keyframe actions.
Version 4.5.1 supports exporting multiple animations into a single file, if you have one character with multiple animations, you can export all animations by changing the 'Animation Type' option to 'All Actions' or 'All NLA Tracks' when exporting. 'All Actions' means exporting from 'Action Editor', while 'All Tracks' means exporting from 'NLA Editor'.
If you want to get a concatenated action, you need to enable the 'Concatenate All' option as well, the exporter will concatenate all actions or all NLA tracks into a single action automatically, then export the single action into FBX file.
But exporting multiple animation actions has a few limitations:
- There should only be one armature in the scene.
- There should only be one mesh which has shape key animations in the scene.
-
You must arrange all shape key actions in the same order of corresponding armature animation actions.
- You must clear all incompatible actions from the 'Action Editor' before exporting.
You usually don't need to bake animation before exporting, just export when you are ready.
If you find that the exported animation is not as the same as it in Blender, try baking animation before exporting, for baking animation can always fix various issues.
Raw Keyframe
Version 6.0.0 supports importing and exporting basic raw keyframes, this means that you can modify animation and exchange modified animations between different 3d softwares now.
But there are some limitations:
1. It only supports mesh, empty node, camera, light and FK based meta rig, IK based advanced rig is not supported, for there are usually no raw keyframes on deform bones of an IK based advanced rig.
2. It always ignores the BEZIER handle information, so it will use the default BEZIER handle values when importing and exporting BEZIER interpolation.
In my test, though it works well in default mode, if you want to keep maximum compatibility, I recommend that you enable the 'Raw Keyframe' option and disable the 'Optimize For Game Engine' option when exporting; enable the 'Raw Keyframe' option and set the 'Rotation Mode' option to 'XYZ Euler' when importing.
Invoke The Add-on Via Python Script
To invoke the add-on via Python script, you need to get the full API of the current version, for the parameters may vary with different versions.
To obtain the full API, switch to ‘Python Console’ windows.
Type ‘bpy.ops.better_export.fbx’ and type the ’Tab’ key, Blender will auto-complete the full API of the exporter.
You need to fill the 'filepath' parameter, and invoke the command in Python script.
Type ‘bpy.ops.better_import.fbx’ and type the ’Tab’ key, Blender will auto-complete the full API of the importer.
You need to fill the 'filepath' parameter and the 'files' parameter, and invoke the command in Python script..

License
The add-on is under a dual-license.
The Python code of this add-on is under the GPL license.
The add-on does not interact with FBX SDK, instead, it interacts with a universal text format I invented, which is elegant and plug-in friendly, supports all 3d softwares.
The product package also includes a command-line utility, which interacts with the universal format, and convert it to FBX format, or vise versa.
The command-line utility is written in c++, which links to FBX SDK to generate the binary file.
The add-on uses the command-line utility via a simple system call.
Note: The command-line utility is NOT under the GPL license.
The command-line utility respects Autodesk FBX SDK license, which requires the developer to put the following statement in the online document.
"This software contains Autodesk® FBX® code developed by Autodesk, Inc. Copyright 2014 Autodesk, Inc. All rights, reserved.
