Why does the converter convert all older materials to “metal”? It is functionality useless because of this glitch if one buys lots of models as I do with lots of materials - both V-ray and Corona 6 models.
I've seen a couple of scripts that solve some of the problems: https://gist.github.com/ejut/68f88069f7b2fbb4765d41a2803693fc#file-coronaconverter-ms and a metalness switch script (but what about metal ones that I need to keep?)... They only go part of the way.
Should I just downgrade to Corona 6? Just use V-ray models as is with V-ray materials.
It is also a steep learning curve to get to 7 which only has marginal improvements in my opinion.

I just use the old converter v1.45.
Not up to speed on the new PBR materials🧓

The updated converter has an option to force all converted materials to be non-metal, which means more materials will convert as expected (there might be a few, that should be metal, that would then need some manual adjustment). The reason for it is that the materials being converted from are set up with some poor, non-realistic values that don't translate 1-to-1 into a truly realistic material like the new Corona Physical (crazy high IORs and such).
