Nah, it's easier: The 2020 plugins work for 2021 as well so that converters can access at least all materials. Just copy over <MaxDir>\Plugins\Nvidia\* from a 2020 installation to Max2021 and then open scene and convert to Corona - done.
Edit: Hmm the converter does not convert the Arch&Design materials. I could have sweared this has been my setup to convert mr objects. I can see the material, but the converter does nothing - have to investigate.
Edit: No idea why it is not working (any more?) here. I can access the materials, but the Corona converters (old 1.45 one and current) do nothing. Using Max2020, converting works.
Good Luck
