Rhino 6 can give the following errors in our connection panel:
Failed to initialise HDR Light Studio
Will be shown if the initialisation call to HDR Light Studio fails.
This is most likely due to unsupported version mismatches. i.e. the Rhino connection and version of HDR Light Studio are not compatible.
To check which versions to use together - see our PDF compatability chart here.
Cannot locate HDR Light Studio installation directory
Will be shown if connection cannot find the HDR Light Studio environment variable or the dll.
A reinstall of the main HDR Light Studio application is needed (and a restart of the computer to be sure).
