Why export of ADM files in Dolby ATMOS Renderer panel does not work with External Dolby Atmos Renderer. The file is empty.
If you do the Atmos session correctly, it will export correctly and anyone with Dolby Atmos Mastering Suite, Production Suite, or Nuendo 11 can open it and have all the tracks and automation appear. Took me a few tries. Make sure your beds are no larger than 7.1.2. I had tried doing a group track at 7.1.4 and I think that may have not worked for the export either.
