The trial lasts 14 days and starts as soon as the software is installed.
The only functional difference between the trial and a licensed version is when inside of the trial you cannot save .vrg-project project files (your node graph). This function is unlocked with a license.
Just looking for the latest version?
If you have a license and are looking for the latest version of VectorayGen, fill out the form above to download the software as the "trial" is no different than a licensed version. You can then enter your key under the "help" menu within the software.
Downloads aren't available on mobile, sorry!
