V-Ray for SU "Barn Door Effect"

[raymond_olive]

Hello,

I am new to the Forum, so if I have posted this in the wrong location I apologize in advance. I am hoping to get some detailed information about the "Barn Door" effect for the spotlight in V-Ray. I have tried multiple settings to get the feature to work but the light still renders as a circular spot. Any recommendations on how to approach the setting? What information do you input?

Kindest,
Raymond

the input is radians, not degrees. It also depends on what you have your penumbra angle set to. Just as an initial test, try setting the penumbra angle to 0.5, and each barn door to .34. It appears we need to update our default values for the barn door parameters.
