Following this document works great for creating a line trace. But I can not figure out how to make the red line/box that is visible disappear. I have changed my “Trace Channel” to “Camera” but it still shows the red location of my line trace. Is line trace only used for debugging or is it still used when publishing? How can I hide the trace or what is the alternative?
