V-Ray V-Ray for 3ds Max Issues
1

Hello,

We ran into a small issue with some of our nodes. They couldn’t render via command line.
The error popup message below appears when opening 3ds Max 2023.1, with Vray 6.00.04 (Stable):


---------------------------
V-Ray
---------------------------
An error occurred during initialization:

chaos_networking: C:\Program Files\Chaos Group\V-Ray\3ds Max 2023\bin\networking is not a valid directory

It is recommended that you exit the application and reinstall V-Ray now
---------------------------
OK
---------------------------

Manually creating the directory “C:\Program Files\Chaos Group\V-Ray\3ds Max 2023\bin\networking” solves the issue and they can render normally.

Note that most computers could render without this folder created and uninstalling / reinstalling Vray couldn’t solve the problem.

Thanks for your hard work and for the great update!
Jo.

I have this problem too but I cannot create the path to solve it because the path is nonsence. Where is tshis chaos_networking stored so I can change it?
Thx

For recent 3ds Max versions it should be here: C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2025\bin\networking

Hmm, Im using arbitrary installation so this path is empty for me. But in my server dir path there is only file called chaos_cacert.pem with some certificates inside, but not chaos_networking path definition.

I’ll get the tech support to investigate. Hang on.

I need to change this path. Its not stored anywere inside max paths configuration nor enviroment variable.

Ok thanks.

Open a support ticket. They’ll take care of it.
