Join Craig Barr for an in-depth discussion in this video Adding a bloom effect, part of Unreal Essential Training (2016).
- If we're working with our scene and we want to add some interesting post processing effects to the view port or for that matter for how the scene will interact with the viewer, we can see how tone mapping in this scene has affected the overall viewing experience. Well, a couple of interesting things that we can do here as well as with post processing effects include how we interact with the light bouncing, specifically with reflections within the scene. So if we click on this car and we zoom in, we can see that as we tumble around, our car has these nice reflections on it.
So if we tumble towards the light, we can see that we're getting this nice reflection here but it would be nice to add a little of an effect to this that will be dynamic to the viewer that is how the light bounces off this reflective object to the camera and we want to actually produce something that is referred to as a bloom effect here and we can do that live in the view port. So let's just click actually anywhere and we'll just hit Escape so we've deselected everything. We're going to go underneath our Show tab up here on the left in our view port and we'll come down to Post Processing.
Now we can see in the bottom here that we have Tone Mapping engaged. That's important. We need that to get this effect. We can also come up to the very top and click Bloom. Now you see a little bit happened there in the view port if we click that on and off. We're getting that kind of glare or a bit of that fall off there with the light. So let's move out of this scene here. I'll just hit Escape so I'm not selecting anything inadvertently there and if we tumble around, we don't see anything that much different, but where we're really going to see a bloom effect is if we get the light bounce off a reflective surface in kind of that 90 degree light bounce indirect into our eyes essentially or directly into our camera from that field of view or that angle of view.
So if we tumble around here, we can see that we're getting the light reflection now giving us that really nice kind of bloom effect and that really gives a little bit of a more realistic feel to the scene in the sense of something that you would see kind of in the real world there where you get that direct bounce of light. And that is applicable here or affected by this post processing flag bloom. So we can certainly get some really interesting effects here in the view port in Unreal Engine 4.
