Why does the converter convert all older materials to “metal”?

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).
