Why are the texture braking when i export the textures from roblox to blender?

my bandana mask looks like this in studio

and like this in blender

why are the meshes like this!? any help appreciated.

oh and also my jacket on my roblox avatar seems to glitch out blender so if there any fixes for this please let me know but i dont really mind because i dont need the jacket

probably when you import it in blender, blender enables double sides on this mesh, so just try to disable it

Try using this video:

Hope this helps!
