Old Max scene files crash on opening in Max 2020

[Bruce Hart]

I've been going through some old files sitting in our library and finding that many of them will crash Max 2020.3 upon opening. The same file will open OK in Max 2018. It is possible to merge the file into Max 2020 without crashing, but not open directly. These files were made using Vray 3.x or lower. Not sure if this is a problem with Vray or with Max itself. I would suspect the latter. A small example file is attached. There will be maps missing but hopefully you can see what is going on.

Edit: I'm using Vray Next 4.03.01

I am able to open the file without crashing with V-Ray 4.30.01. Try resetting your 3ds Max to its default settings by renaming the ENU folder (i.e. ENU_old; located here: C:\Users\<username>\AppData\Local\Autodesk\3dsMax\ 2020 - 64bit\). Note that this would remove any user customizations that you might have (Max will create a new ENU folder).
