you have done it again, it took me almost 5months to convert old materials ( i have custom made libraries with 1000+ materials for my work ) to new ones since there were missing components in the material branch and it was crashing.
I was working for like a year now normally without problems, after the new update 7.3 the nightmare started all over again. I open my scene ( working with at least 6-7 per day ) and when i open Material editor… BOOM… Crash… why this is happening? you should have a proper migration when new releases coming out to fix the current material errors. PS. i only work with VRAY materials.
Mind if you attach/send the material library so we can troubleshoot?
Can you also provide a crashdump file? This will give us a bit more clarity. Thanks.
Hello again and Happy New 2026!!! so i will post here the error screen captures and also the dmp file so you can check it! The problem can be somehow bypassed if i assign Scanline as material editor renderer, because if I use Vray for materials then on some of them, even with a simple selection, i crash!

this one is the previous major update i had done with far less materials in it, from the older problem that came up again after one major update of the past you made. From Vray Next to vray 5 and up.

Thanks for the provided files. By the way, do you have issues/errors when rendering (anything)? I’m not getting crashes with that library file, otherwise. I’ll talk to the devs to look at the dump for more info.
Hello, i forgot to mention that the crashes happen mostly when i have the Vray IPR window open and running, in general, besides this issue that follows me years now i have no other problem, i have 30years of experience in 3D and for the past 10 years working 99% with VRAY.
This problem started a couple of years after updating Vray to newest versions, 1st incident was when I upgraded from Vray Next to Vray 5 and up. On Vray 6 i had no issues after i spent hundreds of hours to convert my materials to non crash versions. Now it happened again.
It is really frustrating to have a working plan that works and suddenly after updates i get my work interrupted and i cannot bare to change again the materials. I just apply Scanline in material editor renderer and then i copy my material settings without IPR open and i delete the old materials while replacing it with the new. As you can understand this is not a all productive. I have uploaded a single material library with 100% the issue poping when i have Vray assigned as Renderer and the crash happening when i open the material editor and pick the white plastic material. I work mostly with Chaos products, VRAY, Phoenix and i have also TYflow and HDRI light studio installed.

Thanks for the feedback and file. The crash is reproducible with that material. Will report back with more info.
Well, the crash is caused by the missing plugin in question. Not sure if you can fix the materials easily. Best you recreate the affected ones. Otherwise, the devs told me that it’s possible to avoid such crashes and possibly print an error/warning instead.
EDIT: Logged it (VMAX-15377).
Well, that is the whole problem, i use no 3rd party plugins besides TYflow and the materials (All of them) made the same problem as i mentioned again in the past. It is a clear Vray materials with no plugins used and it is embedded in the materials so the problem is something that your Devs should explore deeper. It is frustrating and disappointing to have these problems anytime you updating Vray, all those scenes i got the problem with were working just fine, ( after i updated the materials from the old ones ) its not productive nor efficient to do all the materials again and again in every update… As i said i have done hundreds and i reuse them. At the past i made also materials with Arnold, the embedded renderer in 3dsmax and after updates nothing weird happened, the materials kept on working fine. Please notify me if you find something with the devs.
