Open your web browser and type where servername is the IP address or the name of the machine where the V-Ray license server is running. If the license server is running on the specified machine, try to connect to it manually from a web browser.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).You can do that from Start menu > Programs > Chaos Group > V-Ray for 3ds Max > Licensing > Administration > Change V-Ray client license settings. Check that the license server settings are correct.Solution: There are several things to check:

Problem: The ActiveShade window displays a message "error: Could not obtain a license (10061)" and remains black.Ĭause: This error means that V-Ray RT could not connect to a working license server. It looks like this is a Vray specific error message, so I checked their website and found this article.

I want to extend a warm welcome to the Autodesk Community! Hello for bringing your question to the forums, it looks like you are visiting as a new member to the 3DS Max forum.
