I'm trying to export some data to SVX format, and upon upload I get the error message "We're unable to process this file. Check your file for errors and click 'Update File' to upload a new version.". I've tried to make my data as close to the sphere tutorial (http://abfab3d.com/svx-format/), including the same manifest file and same file names. I've attached the SVX file... can you see anything wrong with it? Thanks for any help that you can provide.
