Exactly, I know how to save the skin. But the problem is different, see the description. The skin will not save to the lfs server. And if it does, it's wrong. For example, it has a red filter over it and so on. After updating my skin page, the uploaded skin completely disappears.

After buying the credit, I only uploaded a test skin of the vehicle as a test. After deleting it and creating a new one, the skin is not saved on my web page and when I preview it and show the preview, the skin is broken. Both in color and in the way it looks. After leaving the site it disappears completely.
