Object completely distorts when imported from Blender

Hi-!

I’m going to try to be as concise as possible. I downloaded a model online and attempted to add a piece of clothing sculpted from the model. I copied the model and scaled the body-part to a slightly larger size. After creating a UV mesh, I tried to export the file as an FBX to unity using the settings below. Instead of the model having these stockings, it seems the mesh has exploded into sharp points. I’m not sure if it’s an export setting, or perhaps it’s something from copying the body and using that?138615-notsupposed2unity.png

The first image is from blender, and the second is the same file exported into unity. Because I can only attach two files, I have my fbx export settings in imgur links here: https://i.imgur.com/PknwqPL.png https://i.imgur.com/VliiKDP.png https://i.imgur.com/TTOiKBh.png https://i.imgur.com/3IFPbUJ.png
I appreciate any replies helping me with this issue!

I actually found the reasoning behind the distortion. The previous model had shape keys associated with it, and so when I copied and created the stockings, the shape keys duplicated and were on the stockings as well. After deleting the shape keys from the stockings, it exports perfectly!
