Material Library Browser Problem

[roysgi]

Hey.
The problem exists in Max 2020.
In Max 2022 that is also installed the problem does not exist.

See Attached.

Thanks

This of course refers to the vray Material Library Browser

Hi could explain a bit more what you did before the error started showing up. This error means that the file is saved by a newer version and now in the older can't be opened - this is expected. Maybe you saved a custom version of this material with 3ds max 2022?

Hey.
I have two max installed: 2022, 2020 and both have vray installed
Can't say exactly when the problem started - probably after installing one of vray's updates.
This refers not to custom material but to materials that are in the materials library that come with the vray-vray material browser.
The problem is with some materials not with everyone
The materials with which this problem is: carpaint, diagrammatic, emissive
And they also do not appear in the browser - see attachment
With the rest of the materials like bricks etc. there is no problem.
Thanks

I suggest to delete all of the old Material Library files/folders and download it again manually. You can download it manually by executing the mtllib.exe file located in C:\Program Files\Chaos Group\V-Ray\3ds Max NNNN\bin. For 3ds Max 2022: C:\ProgramData\Autodesk\ApplicationPlugins\VRay3ds Max2022\bin.

Do not forget to check and eventually fix you project paths in 3ds max:

Thanks.
I deleted the materials library and reinstalled vray and it solved the problem.
Another thing: Is it possible to view image (see attached). Even before that it did not work with the vray material library. The path is set correctly

Hi this is a known issue. We have a report for this in our system under VMAX-11189.
I will add your request and bump it's priority

This is due to adding/refreshing materials with the script (under the "Add to library" button), but doing so from a max version higher than the one you tried reading them from.
It's a Max thing (the non-backward compatibility), and the only way you have to ensure it won't happen again is by doing all the addition/conversion from the lower Max version you have available.
Or, of course, use the library in the same, or higher, version of Max you created/refreshed it with.
