How quickly is the software delivered?
The software itself can be downloaded instantly via Internet once an order for you is processed by Chaos Group (you will receive applicable notification emails once it is done). However, in order to start using the software you need to activate your license.
If the license you have purchased is to be delivered on a new dongle, you might have to wait for it to get shipped to your address by the local reseller. Please, stay in touch with your preferred local V-Ray reseller so to confirm shipping details.
