Title: Corona 12.1, Archive Issue
Post by: Sasan Ezazi on 2024-12-06, 23:15:10
Hey Guys!
When I archive my scene with the newest Corona version, my coworkers can't open it with the oldest Corona, like 12 hotfix 1. Also, when I changed my Corona to 12 hotfix 1, the files crashed at startup!
Is there any solution that exists?
Thanks

hi,
Do you use corona cameras in your projects? I noticed a backwards compatibility issue between corona 12 update 1 and corona 12 hot fix 1 if you use corona cameras. The only solution I found is to use only physical cameras and then everything opens without problems.
I hope this can help you

It is never guaranteed that a file saved in a new version of Corona will open in an old version - 12 Update 1 is a prime example, because there are new things like Automatic Exposure and White Balance that exist for cameras that do not exist in earlier versions, so the earlier versions can't read the data. Corona will warn you if you are about to overwrite a scene saved with an earlier version and prompt you to make a backup of the scene made with the earlier version. It's always worth just manually being sure to create a new copy of any scene with any new version of Corona, and leave a previous untouched old version on disk.
