Nate You actually read it right, I didn't explain it clearly. I was exporting atlas,png texture,and skel data, and trying to import them into the file that I attached in the link, and i ran into a problem where i am not able properly import the skel data file, atlas and texture were working fine, but once,I imported the skel data, it broke the animation and texture, the game cannot read it. I redo them by using by using the same version of spine as the asset file originally like you suggested,but still ended up with the same thing. I afraid that the method that i use to import the files might be the problem, I am using AssetBundleExtractor the import the files.
