Corona 12 doesn't render scenes created with version 11

[Riccardo.3D]

I use 3dsmax 2025.
I installed Corona 12 and it wors perfectly with new scenes but not with scenes created with 11 version.
What can I do to solve the problem?

You'd need to give us a lot more information :) All scenes we've tested from earlier versions work fine, clearly it wouldn't be released if it generally didn't render old scenes. So we'll need to know about your old scenes, and what you mean by "doesn't render". Is there an error message? Do they render all white, all black? Does it crash on loading the old scene? Easiest thing  to do is to send in one of those scenes that won't render, via ticket, along with that extra information on what happens, to https://support.chaos.com/requests/new.

This case was solved through support ticket #266705. The solution was to remove legacy Mental Ray assets using the 3ds Max Scene Converter. (not the Corona Converter!)
