My computer locks up and freezes while rendering

Problem: The computer running V-Ray RT locks up and freezes when starting ActiveShade.

 

Cause: This is most likely a hardware problem. V-Ray RT cannot cause system freeze by itself. The worst that V-Ray can do is crash 3ds Max or the standalone render server.

 

Solution: Check your memory chips and/or your CPU temperature, especially if your processors are overclocked.

My computer restarts when using V-Ray RT

Problem: The computer running V-Ray RT restarts when starting ActiveShade.

 

Cause: This is most likely a hardware problem. V-Ray RT cannot cause system restart by itself. The worst that V-Ray RT can do is crash 3ds Max or the standalone render server.

 

Solution: Check your memory chips and/or your CPU temperature, especially if your processors are overclocked.

I get a "V-Ray RTEngine DLL not found" message

Problem: The message "V-Ray RTEngine DLL is not found!" appears in the ActiveShade window and the scene is not rendered.

 

Cause: This message means that there is something wrong with the installation of V-Ray RT.

 

Solution: Reinstalling the application may fix the problem.

The ActiveShade window remains black

Problem: The ActiveShade window remains black; the message "Waiting for image data..." may be displayed.

 

Cause: This may happen if the initial transfer of the scene data to the render slaves takes a long time. It may also happen if there are no available V-Ray RT render servers to perform the rendering.

 

Solution: There are several things to check:

 

• Check the Render servers dialog in the V-Ray RT render settings and make sure that there is at least one render server selected, or that the Auto-start local server option is enabled;
  
  
• If there are render servers selected, check that the V-Ray RT render server application is started on those render slaves;
  
  
• If the V-Ray RT render server application is running, check its console window for any error messages.

If all of the above points are ok, try restarting the V-Ray RT render server and then the ActiveShade window. If the problem pesists, contact our support team at vray@chaosgroup.com

I get a "Could not obtain license (10061)" error

Problem: The ActiveShade window displays a message "error: Could not obtain a license (10061)" and remains black.

 

Cause: This error means that V-Ray RT could not connect to a working license server.

 

Solution: There are several things to check:

 

• Check that the license server settings are correct. You can do that from Start menu > Programs > Chaos Group > V-Ray for 3ds Max > Licensing > Administration > Change V-Ray client license settings.
  
  
• If the license server settings are correct, make sure that the license server is really running on that machine (if the license server is specified as localhost or 127.0.0.1, this is your workstation).
  
  
• If the license server is running on the specified machine, try to connect to it manually from a web browser. Open your web browser and type http://servername:30304 where servername is the IP address or the name of the machine where the V-Ray license server is running. If you do not see the license server web page, or an error is displayed, it may be that the connection to the license server is blocked by a firewall or an antivirus program. You must change the set up of this program to allow connections to the license server.

If all of the above points are ok, try restarting the license server and then the ActiveShade window. If the problem persists, contact our support team at vray@chaosgroup.com

I get a "Could not obtain a license (-98)" error

Problem: The ActiveShade window displays a message "error: Could not obtain a license (-98)" and remains black.

 

Cause: This error means that, while V-Ray RT successfully connected to the V-Ray license server, there are no licenses for V-Ray RT on it:

 

• You may be using an older version of the V-Ray license server that does not support V-Ray RT licenses;
  
  
• You may not have any licenses for V-Ray RT on the dongle attached to the machine where the license server is running.

 

Solution: Check the license server status page to see if you have a license for V-Ray RT. Contact our support team at vray@chaosgroup.com for further assistance.

I get a "Could not obtain a license (1002)" error

Problem: The ActiveShade window displays a message "error: Could not obtain a license (1002)" and remains black.

 

Cause: This error means that, while V-Ray RT successfully connected to the V-Ray license server, there are no free licenses for V-Ray RT available. All the licenses for V-Ray RT are currently engaged by other machines connected to the license server.

 

Solution: Check the license server status page to see which machines are currently connected to the license server. Close the 3ds Max ActiveShade window on one of these machines to free a license for V-Ray RT.
