[Max] Bug Reporting / Re: Corona 12 crashes all previous Coronas
« on: 2025-06-12, 23:50:48 »Hello,
Yes, its exactly about the Corona 12 crash affecting all earlier versions of Corona. It would be very cool if it would worked as it did before - you just needed to reset F10 Corona render settings - and it was all.
But now it just leads to full crash of 3dsMax. And the only way to avoid this - its to change the current render and loosing all the global settings.
Its too sad if its impossible to fix. Because of these crashes all sites of models placing cant normally work with Corona 12 and have to reject such scenes and it doesnt help to popular of Corona 12 amomg model makers.
Thanks for the interesting solution — we hadn’t seen it before, but we’ll definitely give it a try!
Hey corona team! 👋
We also wanted to share something important for the Corona team: if someone accidentally updates to Corona 12.1 or 12.2, they won’t be able to open the same scene in earlier versions (we tested with Corona 11).
We were a bit surprised to see so few discussions about this on the forum. When we ran into the issue, we expected it to be widely known and perhaps already resolved — but apparently not. In fact, our entire team encountered it.
The tricky part is that Corona becomes incompatible with all previous projects. So if just one artist updates, the whole team is forced to switch versions, regardless of where the current projects stand.
So, friends — if you’re planning to update, do it with caution.
By the way, based on our experience: if you merge the scene into an older version without the CoronaCamera, the global crash and 3ds Max shutdown don’t happen. In all other cases, it crashes every time.
Hope this helps other users — and maybe the Corona team — to improve future compatibility!
