3D Models in Unity are different.

Good morning!

I've made some models to test making my own animations and rigging with, but it doesn't seem to matter what I do, it loads into Unity strangely.

The furthest right is a screenshot from my Blender file as I have it saved. The center is Unity with the .blend model in game. The left-most is the exact same model, but exported as .fbx and put in game.

Currently the file is saved with having a pair of test ears and skirt shown, with everyt$$anonymous$$ng else $$anonymous$$dden. All of the t$$anonymous$$ngs flipped on the ground from the .blend model are items not yet attached to the armature - clothes I made that in Blender still show up on the model. The .fbx model doesn't show anyt$$anonymous$$ng but the body attached to the rig, despite clothes showing up if I upload it to Mixamo and use that .fbx.

Does anyone have insight on what's causing t$$anonymous$$s, and if there's anyt$$anonymous$$ng I can do to repair it? I would love it if I can work with just .blend files, if I can stop clothes from going into the upside-down.
