phtcloud Thank you for sending the spine.log file and the export settings JSON. When I first read your explanation, I wasn’t entirely sure about the specific issue you were encountering, but I now fully understand the situation. So, no errors occur, but some images are missing during the texture packing process, correct? This is a known bug, and we have an issue ticket for it here:EsotericSoftware/spine-editor849
As you can see from the ticket, unfortunately this issue has been known for about a year, and regrettably, there is currently no estimated time for a fix. The cause is that the same image is being referenced by multiple mesh attachments while Polygons packing is selected in the Texture Packer settings, which causes the mesh hull to trim the image.
As a simple workaround, switching from Polygons packing to Rectangles packing will resolve the problem:
If you prefer to keep using Polygons packing, you can instead avoid referencing the same image from multiple meshes by using separate image files. In your project, for example, a single image containing both eyes is split into two meshes using mesh hulls. You can prevent the issue by preparing the eyes as separate parts from the beginning—by editing them as distinct elements in your image editing software such as Photoshop—and not cutting them out using mesh hulls.
We apologize for the inconvenience. Please try one of the suggested workarounds.
