Why can't I get depth of field to work?

I can see that depth of field works in the gltf_viewer sample, but I can't seem to get it to work in my own project. I enable depth of field using View::setDepthOfFieldOptions, I set the camera aperture to f/1, set a large focal length, and set the focal distance to be very different (much smaller or much larger) than the actual distance from the camera to the object, but nothing gets fuzzy. I also tried cranking up the cocScale parameter. Any idea what I might be missing? Or ideas on how to debug it?

@romainguy Sorry, I figured it out. For some dumb reason I had turned off post-processing, and apparently that is needed for DoF.

Oh, yes indeed. Turning off post processing turns off many features. It's less useful to do so now that we offer a way to choose the tone mapper.
