Learn how to mask a spot light with Arnold filters.
- [Teacher] We can now finalize the look of our key light.…It's going to represent sunlight coming through…a window behind the camera,…and we want to achieve the effect of two swaths of light…coming in through a window pane similar to this one.…We can use a barn door filter…to crop the edges of the spotlight.…We can use a gobo or a cookie…to further silhouette the light.…Or, in fact, we could even use gobo…to project a color image.…
Let's open up the Arnold render view…if it's not already open,…and I want to render the perspective camera in this case.…Just for testing purposes, it will be easier to see…how the barn door and gobo are affecting the spotlight.…Select the light,…and in the Attribute Editor,…scroll down into the Arnold section.…And, at the bottom of that,…is a section labeled Light Filters.…Click the button labeled Add.…
In the pop-up dialog, choose Barndoor…and click Add.…aiBarndoor1 is added to the list of Light Filters,…and aiBarndoor1 is available as a node tab…in the Attribute Editor.…Click on that tab, and we can now adjust…
