Spine has limitations when exporting extremely high-resolution images due to the constraints of the software and the underlying graphics technology, such as OpenGL. For very large resolutions like 47345x44701, you may encounter issues with exporting at 100% resolution. A common workaround is to scale down the root bone before exporting, which effectively reduces the resolution to a manageable size. Alternatively, you can export at a lower resolution and then use software like Photoshop to upscale the images, though this may not preserve the original quality.
