Issue When Exporting From Blender to Unreal

Hello, So I have been having trouble exporting my Skeletal Mesh fbx file from blender and then importing it into unreal. For some reason, the front part of the mesh is extruding. I don’t know why, but in blender, the mesh looks perfect.

Here is what it looks like in unreal

Any suggestions? Thanks for reading this.

Seems like some issue with the weight-painting (e.g. not all vertices got 1 weight). Should be fixed if you normalize it in Blender. If this does not help then select all vertex groups and doublecheck some painting failures (as they could happen for example if you paint in top view on the head and get a bit of the feet below by mistake).
