I have a number of objects parented to one another in Blender. I want to export them to Unity. I've used an FBX export (many times, successfully, for single objects in the past) and ensured that all the objects are selected. I have also confirmed that all scales/rotations/locations have been reset, for each object, and checked all normals are pointing the correct way.
I export to Unity, using FBX 7.4 binary, with "selected objects" checked.
The result is the picture - all that stuff is supposed to be connected.
