In Unity this is equivalent, and may be changed to, the original scale (-1, 1, 1) and rotation (0, 0, 0). Example: scale (-1, 1, 1) and no rotation is imported as scale (-1, -1, -1) and rotation (-180, 0, 0).

Negative scaling is imported with a different but equivalent transform in Unity.blend files don't work with Unity Cloud Build. it's a no-go for publishing packages in the Asset Store.Requires Blender to be installed in the system, so: blend file directly in the Unity project? Why not use the 'Bake Axis Conversion' option in the Unity Import Settings?ĭoensn't seem to work properly with Blender-generated FBX. Objects beyond the 2nd level keep receiving unwanted rotations and scalings when imported into Unity. This option doesn't work with object hierarchies of more than 2 levels.

Why not use the 'Experimental - Apply Transform' option of the default FBX Exporter? As the objects in the FBX already have a rotation of X+90 then the undesired rotation is canceled and everything gets imported correctly. When Unity imports the FBX file all objects receive a rotation of -90 degrees in the X axis to preserve their visual pose.

Finally the scene is restored to the state before the modifications. The modified scene is then exported to FBX using Blender's built-in FBX exporter with the proper options applied. This is done in the root objects, then recursively propagated to their children (as they inherit a -90 rotation after transforming their parent). The exporter modifies the objects in the Blender scene right before exporting the FBX file, then reverts the modifications afterwards.Įvery object to be exported receives a rotation of +90 degrees around the X axis in their transform without actually modifying the visual pose of its geometry and children. The File Browser exposes selection and armature options:

The full hierarchy is properly preserved and exported, including local positions and rotations.

Enable the add-on by checking the enable checkbox.Įxports all Empty, Mesh and Armature objects in the current scene except those in excluded collections.

In Blender go to Edit > Preferences > Add-ons, then use the Install… button and use the File Browser to select the add-on file.

Clone the repository or download the add-on file blender-to-unity-fbx-exporter.py to your device.

Exported FBX files are imported into Unity with the correct rotations and scales. FBX exporter add-on for Blender 2.80+ compatible with Unity's coordinate and scaling system.
