MP4s and GLB (3D files)

If you want to have a 3D image that can be interacted it by anyone, you just need to upload a .GLB file as one of the preview images.
MP4s are also accepted as a means to play videos if the user wants to watch them.
You still need to upload a basic image as the display image if you choose either of these types.
If your file name contains special characters like $%*&#@()[] in the file title or any non-English characters, it will not upload.
If you are having issues uploading, disable other extensions on your browser except for MetaMask. Close all Mintable tabs, refresh, and try again.
