Title: Return problem Corona 7 to Corona 6
Post by: IamAlive on 2021-10-28, 14:25:42
Hello, I worked 3d max for Corona 6, I decided to try Corona 7 in a 45-day unlimited demo mode
After 45 days, returned to Corona 6 and all the scenes of spoilage/
since there is no way to return Corona 6, because materials PhysicalMaterialMtl  not convertible to CroronaMtl
I have no financial opportunity at the moment to purchase Corona 7, what should I do?!!!
I live in a poor country!!

Corona 7 warns you (and offers to make a copy) before saving over a scene created in an earlier version of Corona. If it was a new scene created in 7, then of course there is no warning. Compatibility never works in reverse, where something created in a new Corona will work in an old Corona, so never ever create a scene in a newer version if you will have the need to go back to an earlier version at any point (there are often under-the-hood changes too, even if there is not a jump like the Physical Material).

You can start a new scene in Corona 6 and Merge the contents from the Corona 7 scene, and redo the texturing on the imported geometry to use Corona 6 materials. BTW, Corona 7 costs no more than Corona 6, it's all part of the same subscription, you can use any version you like while that is active.

Is there is a way to convert CoronaLegacyMtl (v7) to Corona Mtl (v6)? They seem identical

It is the same material, just with different names in different versions.

And despite that, I can't reuse any CoronaLegacyMtl in Corona 6 and there's no way to convert it at the moment? Just why?

I am afraid it's not possible at the moment for various reasons, but we do have user feedback logged in order to further improve the usage of Corona converter in the near future. Please feel free to report and inconsistent conversion types to us so that we can further investigate and rectify.

Why what? Backward compatibility was never guaranted between major versions. If you want to try V7, make sure that you make copys of your scenes with Corona 6, otherwise you're asking for trouble.
