I want to control the size and barn open and other properties of the light but the rectangele indicator is not showing up, even after selecting it
Hello Moaz,
I’d first check that your ‘Source Width’, ‘Source Height’, and ‘Barn Door Length’ are not small values. (The visualizer can disappear behind the light icon if those are too small)
You can also click the cog icon in the details panel and ‘Show Only Modified Properties’ to see if there might be something else disabling the lines.
Also, try clicking the Eye Icon on the viewport toolbar and selecting ‘Use Defaults’.
