Blender Market – Better Fbx Importer & Exporter v5.2.5

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 2019, Unreal Engine 4/5 and Godot Engine v3.2 with no issues.

*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.
