It sounds like you've correctly imported your JSON file and unpacked the texture atlas, but the images are still not displaying in your Spine project. Here are a few steps you can try to resolve this issue:
Check the Images Path: Ensure that the images path is set correctly in Spine. You can do this by selecting the Images
node in the Hierarchy window and verifying that the path points to the correct directory where your images are stored.
Verify Image Formats: Make sure that the images are in a format that Spine supports, such as PNG or JPEG. Spine cannot load PSD files directly.
Limit Scanning: If you have a large number of images, Spine might not be displaying all of them due to the default limit. You can uncheck the Limit scanning
option to allow Spine to find more than 2,000 image files.
Check for Red Icons: If images appear with a red icon, it indicates they are not used in the skeleton. Ensure that the images are correctly linked to the slots in your skeleton.
Import into Existing Skeleton: If you are importing data, make sure to uncheck the New project
option in the Import Data
dialog if you want to import into an existing skeleton.
By following these steps, you should be able to resolve the issue of images not displaying in your Spine project.
