While importing MVR formatted files, I get a warning and the import does not work.
"Cannot open buffer"
Explanation: This is a formatting issue
Fix/Solution: The file can be misread if components such as labels have double quotes (") in their names. Be sure to remove those before exporting.
Explanation: This is a packaging issue. The file doesn't have both the .glTF and .bin in the same directory. This is most common when transferring files between machines.
Fix/Solution: Zip the glTF file before sending to another device.
