Help Jagged edge in render

Hi All

Having trouble where a strip light is appearing jagged in a 3000 pixel render. I have enclosed the settings and a crop of the image showing the affected area. The angle of the view is set as I am camera matching a photo.

Any help appreciated

Matt

Re: Help Jagged edge in render

There is an option in the color mapping called “Clamp output”, enable this option.
