I recently had a problem with the V-Ray license server on Windows returning and error -200 when I tried to render. It turns out the error is because the VRL service wasn’t running and no amount of reinstall and reboots helped. Thanks to the help of friend I was able to resolve the issue by deleting a folder located at: C:\Program Files\Common Files\ChaosGroup Uninstall the License Server from the machine Then delete the folder <code>C:\Program Files\Common Files\ChaosGroup Reboot the machine to reset the Windows Services Install the License server, it should ask for log in data now.

vrimg files are not associated with any program in Windows by default, they may be associated with the Chaos Group PD Player. Also it doesn’t appear that open with creates an association as expected therefore one may have to use the command line function ftype to achieve the desire association. The general way to associate files using terminal commands is as follows: Open cmd.exe with administrator rights (right-click on the shortcut to get this option) Type ftype extfile="C:\Program Files (x86)\YourProgram.

These are the basic Shadow Catcher settings I use in Modo. The main thing is the Alpha Contribution set to -1 in the V-Ray Object Properties.
