(Report ID=CMAX-1198) That’s what @Avi from the Corona team assured us would be reviewed and solved by the devs in the post regarding the quad menu issue in the latest 3ds Max 2025–2026. Corona completely breaks 3ds Max’s new Menu Editor, and no one seems to care about it.
https://forum.corona-renderer.com/index.php?topic=42892.msg229380#msg229380No updates, no mentions.. just a question into the void.
It’s not Autodesk’s issue, or VRay's, or any other script or plugin.. but Corona’s. When you install a fresh 3ds Max and then add V-Ray, Redshift, Octane, or FStorm... whatever.. the 3ds Max menu works just fine. It follows and saves all commands properly. But once you install Corona, the issue breaks the entire quad menu. And even simply removing those two entries "Open Corona Converter" and "Open Corona Proxy Exporter" has no effect. Because, hey, they’ll still be there no matter what, and they cause problems for all custom quad setups the user tries to build.
@Avi: "Hi, I am unable to reproduce this on my end. Can you please record a simple video showing the problem and share it with me?"
And I shared it.
Seriously, just install Corona on a fresh 3ds Max, delete those two from the quad menu, and check the message log. That's all it takes.
