When using the sequence feature in Spine, if you're encountering a red X on the image in the tree window and a "Missing" image in the work area, it suggests there might be an issue with how Spine is locating or interpreting your image files. Ensure that your images are named correctly and follow the expected naming convention for sequences. Spine expects the sequence images to be named in a continuous order, and any discrepancy in naming can lead to issues like the one you're experiencing. Additionally, verify that the Image Path property for your sequence is correctly set up to point to the directory containing your images. If the path is incorrect or if there's an issue with the naming convention, Spine might not be able to locate the images, resulting in the missing image problem.
It's also worth checking that your images are in a supported format (PNG or JPEG) and that the images path is correctly set under the Images node. If the path is incorrect or the images are not in a supported format, Spine will not be able to display them. If you've confirmed that the naming and paths are correct and the issue persists, it might be related to a specific bug or limitation in the version of Spine you're using, although without direct support or bug tracking, pinpointing the exact cause can be challenging.
