To export from Spine, you should ensure that you have set up your project correctly. When exporting, make sure to check the "Pack" option if you want to generate a texture atlas and PNG files along with your JSON. If you encounter an error saying "Images path not found," it usually means that Spine cannot locate the images in the specified path. Ensure that your images are in the correct folder and that the path is set correctly in Spine. For the error "Error Packing Images," it could be due to missing images or incorrect settings in the texture packer. Make sure all images used in your skeleton are available and correctly referenced. You can find more detailed instructions on exporting in the Spine User Guide.
