Blender To Unity

This blender addon applies axis compensation to nested meshes and hierarchies for export to Unity, resulting in clean gameobject transform.rotation properties.

Download the zip from releases, install using addon manager as usual.

The addon adds two buttons to the Object context menu (right click in 3D view):

• Select Hierarchy is the same as the one in the outliner, allows you to use it in the 3D View.

• Blender to Unity preps an object hierarchy for export. Select the parent / root object of a nested asset you want to export, right-click and choose Blender to Unity.

Make sure to only select the root object of the hierarchy you want to export.

This operation runs the following steps:

1. Selects the entire hierarchy
2. Applies all rotations and scale
3. Starting with the root object, applies 90 degree offsets on the X axis recursively, ignoring every second child object.
4. Selects the entire hierarchy, ready for export.

Export FBX using the following settings:

This was not tested nor intended for armatures or animated objects.
