Downward compatibility

Hello,
when saving a szene build with corona 6 and reopen it with corona 5, there will come a error message like “error in filestructure” or in german “Fehlerhafte Dateistruktur” and file cant be open. Just for letting you know.

Hello,

backwards compatibility is not at this point fully supported, especially after the daily build from 30/6/2020, in which some major internals of the node material system were reworked.

Thank you for understanding,

Hi all,
Isn’t there any solution to reconvert a scene to an old (5 hotfix 2) version..?
There’s a way, a workflow or workaround to recover scene geometry and animation at least..?

The newest stable version (6 hotfix 1) is very buggy.
Tried to render animation and constant lights are inexplicably unstable.
Attachment files are 3 consecutive frames of a moving camera.



Hi all,
I’ve managed to recover scene geometry and animation.

Because of “the new node system saves data in a different format;”, I disabled Corona plugin renaming a dll, started C4D without the plugin, opened the scene, and removed all materials.

Re-enabling Corona, the scene opened, without materials, but successfully.
Hope will help someone else waiting for a more stable version.

I would probably strip the scene of anything related to Corona ie: camera, lights, materials, etc. Switch the renderer to standard and save. Uninstall Corona, and reinstall the version you need. Open the scene again and in theory, it should work. Mind you, I have not tried this.

Have you tested out the latest V7 daily build at all? If not, feel free to give it a go!

hi beanzvision,
thanks for the reply
I didn’t, now I’m in a hurry to recover my work, lately, I’ll surely check it.

Out of curiosity, do you have “Animation (Flicker-free)” enabled at all?

The Above Problem appears to be due to LUT Correction at render time not applied in some random frame.
I had the same problem even @ RebusFarm that are use Corona Version 6.
is this a V6 knowing issue..?
