Gobos are a great way to add interest and detail to your scene. This is how you can set them up in the Octane Universal Light:
Gobos will work with quad, disk, IES and Analytic (quad/disc) light types.
In this example I am using this free gobo pack: https://mschumacher.gumroad.com/l/DkHCV

To set it up enable the Distribution { Texture } setting, and add your image under the texture tab.
I would recommend setting the Border UV setting from Wrap to Black Color or Clamp so that you don’t have an endlessly repeating pattern.
Wrap:
Clamp:
Black Color:
The size of your light will determine how “sharp” your gobo shadows are:
A bigger light will create blurred shadows
