To solve the problem of a mesh not displaying normally in Spine, you can try the following steps based on the contexts provided:
Check Visibility Settings: Ensure that the Images visibility is enabled in the viewport options. If the images are not visible, this could be the reason. (Viewport options)
Check Image Coordinates: If the Images visibility is enabled but the images are still not visible, check the coordinates of the image attachments. If the XY coordinate values are extremely large, the attachment coordinates might be too far from the origin, making them appear outside the range that can be displayed in the viewport.
Check for Negative Scale: If you have applied a negative scale to a bone/slot/image, ensure that Backface culling is unchecked in the Spine settings. When Backface culling is checked, triangles facing away from the screen are not drawn, which could cause the image to disappear. (Backface culling)
Ensure Proper Mesh Conversion: If the issue is with converting an image to a mesh, make sure you are in setup mode and follow the correct procedure for creating a mesh from an image.
Check for Missing Images: If the images are missing from your project, ensure they are correctly imported and linked to the respective slots in Spine.
Premultiplied Alpha: If the images appear with unexpected artifacts, check if you need to enable or disable Premultiply alpha during the export or unpacking process, depending on your specific case.
If after trying these steps the problem persists, it might be helpful to share your project with the Spine team for further assistance, ensuring to check for any confidential information before sending.
