FBX

The FBX (Filmbox) format is widely used for exchanging 3D data between applications, especially for animated characters and complex scene data. It is supported by software such as Autodesk Maya, 3ds Max, Cinema 4D, and game engines like Unity and Unreal Engine.

Blender’s FBX importer supports a broad range of FBX features and is designed to be fast, memory-efficient, and highly compatible with both modern and legacy FBX files.

Import

General

Scale

Value by which to scale the imported objects in relation to the world’s origin.

Custom Properties

Import user properties as Custom Properties.

Enums As Strings

Store custom property enumeration values as strings.

Geometry

Custom Normals

Import custom normals, if available (otherwise Blender will compute them).

Subdivision Data

Import FBX subdivision information as Subdivision Surface Modifiers.

Vertex Colors

Import vertex color attributes.

None:

Do not import color attributes.

sRGB:

Vertex colors in the file are in sRGB Color Space

Linear:

Vertex colors in the file are in Linear Color Space

Materials

Material Name Collision

Behavior when the name of an imported material conflicts with an existing material.

Make Unique:

Import each USD material as a unique Blender material.

Reference Existing:

If a material with the same name already exists, reference that instead of importing.

Animation

Offset

Offset to apply to animation timestamps, in frames.

Layered Animation Support

Each FBX “take” is imported as a separate Action, with each animated object assigned to its own Action Slot.

Armature

Ignore Leaf Bones

Ignore the last bone at the end of each chain (used to mark the length of the previous bone).

Export

To export FBX files use the FBX Add-on.
