There's more...

Something that I'd like to point out with regard to the recipe we've just completed is that it focused on understanding and mastering the use of the depth of field post process effect within Unreal. In order to do so, we've made sure to go over all of the pertinent settings in the Details panel. However, I'd like to point you to a particular setting we haven't tweaked that might be useful in certain circumstances: the Tracking Focus Method.

So far, we have spent the current recipe tweaking different settings, and we've done so after we had previously established the Manual Focus Distance of the camera. However useful that is, there are other times when we know the specific actor we want to be in focus – and it is on those occasions when the aforementioned Tracking method comes into play. Moving away from specifying the actual distance at which we want the focus plane to be, this latest system enables the user to just indicate which actor they want to be in focus. All of the other settings do still play an important role though, as properties such as the aperture or the focal length are still crucial when determining the out-of-focus areas. However, changing to this method when you do know which actor needs to be in focus can save you time from figuring out the distance value you should be inputting. If you want to check it out, be sure to head over to the Current Camera Settings section of your camera's Details panel, and look under Focus Settings | Focus Method.
