In previous versions of blender it was possible to use "toon shaders" in the post-processing render options to render objects with a black outline, as if they'd been drawn around with a pen:
I have a blender file that I created in an older version of Blender that I'm now trying to render in 3.0, but the relevant 'edge' options seem to have been removed from the "Output Properties→Post Processing" options. Ticking the "Freestyle" option to enable the edge options there has no effect.
Have these been moved or removed? What's the simplest way to render an outline without extensive edits to my existing files?
