Maya and Vray Unexpected Internal Failure

[yefri_martinez]

// Error: texturedShader->addOutputFragment("vrayLightGain", "inColor"): (kNotFound): Unexpected Internal Failure

Does any one know what brings up this problem. I try sing the Dome lighting and when I add in a HDR, I get this message. AM using Maya 2019 and well the one year educational Vray.

Thanks, if anything.

This error message sometimes occurs when the environment variables are not properly set. Are you using a ZIP install? If you've just installed V-Ray restart the workstation and try again.
