BlockBench rigging breaks when imported to Unity

[mental crest]

Hi, I need help with a BlockBench to Unity rigging issue. My rig works fine in BlockBench, but when imported into Unity, all model parts break and scatter. I've observed that the elements appear to follow the bone orientations incorrectly. Screenshots attached.

Update: I managed to fix the head on the bottom-left model (see screenshot), but it required rotating the head 90 degrees after several failed attempts. I still don't understand the root cause of this issue or the proper solution.

Did you use gltf?

Okay so what I do to import my shit to unity is:

1. Export to gltf or use Import to Blender plugin
2. In Blender - delete everything but your model (this includes the mandatory blender cube and a random ah sphere)
3. File > Export > FBX and change Apply Scalings from All Local to FBX Unit Scale

I've spent a bit too much time trying to figure this shit out, but it works flawlessly and maintains all the animations. The only thing you should import yourself are textures (if you're exporting manually with gltf)

Yes i try with this ^-^

SOLVED: Thank you both for your help! I found the solution today, and it turned out to be quite simple. The issue was that in BlockBench, the pivot points of each element in my model weren't centered on their corresponding elements. Since I had initially animated without bones, I had moved the pivots around for animation purposes. However, when importing to Unity with bones, this caused everything to break. The fix was straightforward: I simply used "Pivot to Center" on each element in BlockBench, and that resolved the problem completely!
