Are you using duplicates of the exact same eye? If so, only one of them may be exported when Alias(去除重複) is enabled in the texture packer settings. When Alias is enabled, two images that are pixel for pixel the same will only be packed once. However, the skeleton should be displayed correctly at runtime. If you want to pack all of the images even if they have the same pixels as others, uncheck Alias.
Also, please make sure the Export(导出) option is checked on the mesh attachment's properties:

If unchecked, it will be excluded during texture packing.
If the above does not solve the problem, could you please send your Spine project with just the eyes part to us via email? : contact@esotericsoftware.com
