I've tried so many different ways and still the pivot imports with no rotation what so ever. This is important because i've created a mesh from a volume using DICOM data, and I have calculated the angle of the mesh rotation of the mesh generated from the volume, but I can't get the pivot to update to that rotation so that in unity, the pivot represents the actual rotation of the mesh generated. Otherwise all these meshes import to unity with different visual angles, but the pivot rotation is just (0,0,) for all.

I've tried

-having a single object (even just a cube) in a geo node and adjusting the geo's pivot translate and pivot rotate and exporting from Filmbox FBX as well as ROP FBX(didn't work)
-going into the geo node, throwing down a transform and adjusting the pivot translate and pivot rotate (didn't work)
-even tried exporting as .obj.
-adding an AW and trying to adjust @orient

Feeling very defeated. Does anyone have any solutions or at least direction to point me in?
