4. Checking the V-Ray license settings:On the machine where you want to use V-Ray, run the V-Ray license client configuration utility from Windows Start > All Programs > Chaos Group > V-Ray for Maya 20xx for x64 > Change license settings. In the dialog that appears, make sure that the IP address in the License server field at the Primary license server tab is entered correctly and that the connection port is 30304. If you modify any of these settings, you will need to restart Maya.

Note: If the V-Ray license server is running on the same machine as V-Ray you can use localhost or 127.0.0.1 in the License server field.

Symptoms:

Here you can find the list of symptoms and their likely cause when V-Ray could not obtain the license. Please check the resolution part at the end of this section.

Symptoms:

When attempting to render, the Maya status line shows the message "error: Could not obtain a license (10061)" or "error: Could not obtain a license (111)" or "error: Could not obtain a license (61)"

Cause:

V-Ray could not connect to a working license server.

 

Symptoms:

When attempting to render, the Maya status line shows the message "error: Could not obtain a license (-98)".

Cause:

V-Ray connected to a working license server but there are no available licenses for the installed V-Ray version.

 

Symptoms:

When you start the IPR render server, there are no error messages in the V-Ray console, but when a job is sent to the IPR render server there is an error in the console "Could not obtain a license (10061)."

Cause:

No access to the V-Ray license server.

 

Symptoms:

When you start the IPR render server, there are no error messages in the V-Ray console, but when a job is sent to the IPR render server, the error in the console is "Could not obtain a license (-98)."

Cause:

V-Ray connected to a working license server but there are no available licenses for the installed V-Ray version.

 

Symptoms:

When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (10061).”

Cause:

No access to the V-Ray license server.

 

Symptoms:

When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (-98).”

Cause:

V-Ray connected to a working license server but there are no available licenses for the installed V-Ray version.

 

Resolution:

Please go through the checklist below:

Checking the V-Ray license server:

Please restart the machine with the V-Ray license server or dongle installed.
If you are using a dongle, unplug the dongle and plug it again in a different USB port, preferably USB 2.0. Make sure that Windows properly recognizes the dongle and doesn't show an error message. If you receive an error message, please refer to  V-Ray License Server Can't Start in this section.Open the link http://localhost:30304 in a web browser on the same machine. If it looks like the screenshot below, the license server is working.

Checking the available licenses on the license server:
Check the available licenses. You have to have proper licenses for the installed V-Ray version, e.g. if you installed V-Ray Next for Maya, you need V-Ray Next for Maya license. You can check that by entering the respective V-Ray option on the http://localhost:30304 page. You can see all available render nodes and interface licenses, as well as check the borrowed ones.

Please refer to Changing your License Settings page in the Set Up Your V-Ray License section for more information on the type of licenses you need to look for. 

 

Checking the connection to the license server:

If V-Ray is on the same machine as the V-Ray license server, you can skip this step.

To make sure that nothing is blocking the connection to the license server on the machine where you want to run V-Ray, open the link http://<IP_address> :30304 in a web browser, where <IP_address> is the IP address of the machine with the V-Ray license server. If you get a web page like the one below, V-Ray can access the V-Ray license server from this machine. In the example screenshot below the IP address of the machine with the license server is 10.0.0.107

If you get an error message that the web page can't be accessed then there is a network problem that prevents the connection to the V-Ray license server. If you have any firewall or antivirus software running on your machines make sure they are not blocking applications' access to the network or blocking the communication on TCP/IP port 30304. Please contact your system administrator for more information.

IPR GPU is Crashing

Symptoms:  

When rendering with IPR on CUDA, it crashes without showing a specific error message.

Cause:

The scene you are trying to render is too large and the Graphics card memory is insufficient.

Resolution:

You can try to reduce the scene size by reducing the polygon count or by using lower resolution textures. IPR has an option called “Resize textures for GPU” that you can use to automatically resize textures during rendering on the GPU.

Alternately you can upgrade your graphics device with one containing more memory.

 

V-Ray Environment Variables Issues

...

 

Tabs Container

titleWindows

 

Symptoms:  

Right after an apparently successful installation, the V-Ray for Maya plugin loads in Maya, but V-Ray does not appear in the list of available renderers. The script editor shows a number of errors “Could not read V-Ray environment variable VRAY_FOR_MAYA2018_MAIN_x64. Please re-install” or similar.

Cause:

V-Ray for Maya uses several environment variables to find out where various components are installed. The above errors appear when V-Ray for Maya cannot find these variables.

Resolution:

Try to log out and log in to your machine again – sometimes the environment changes are not propagated immediately throughout the system.

 

Uninstallation Issues

...

Symptoms:

The V-Ray for Maya uninstaller crashes and does not successfully complete the uninstallation. After that, a new installation cannot start.

Cause:

There could be leftover files that the installer could not delete, which are blocking the next installation.

Resolution:

Please check if the following files are present and delete them, before attempting a new installation.
For V-Ray 6 or newer versions: C:\Program Files\Chaos Group\V-Ray\Maya 20nn for x64
For previous versions of V-Ray: C:\Program Files\Autodesk\Maya20nn\vray

NOTE: Some third-party Maya plugins store their files in these folders as well. Make sure to delete only the V-Ray files.
