[Unity] Part 4: Post Processing 2

Information

Step 1

In this lesson we'll learn how to use the rest of the Post Processing effects!

Step 2

Continuing from the previous lesson, it's add another effect to our Volume! This time we'll add "Bloom"

Make sure to:
- Click All to enable it
- Set the Intensity to 1, so that we'll see something.

Step 3

We can't check our work yet, because bloom 'Only' shows on objects with Emissive HDR.

So let's select one of our balls, and Enable Emission on it, and change the HDR scale to 2.0 or 2.5

Step 4

Now lets check our work! Divide the Scene/Game views, and move the Main camera into the volume.

Challenge

Step 5

Try applying Emission to your other objects Materials!

Step 6

Let's now actually press Play and see what happens when we zoom in and out of our player!

What's happening is that the Camera that is following and rotating around the camera is sometimes going into the volume box or going out of the volume box.

Step 7

If you want the volume to cover the entire world, we would want to tick "Is Global" in our Volume

Step 8

Now this Post Processing Volume covers the entire world!

Step 9

You can actually have more than one Post processing Volume in the world! Let's extend our platform.

Make a copy of our plane, hold down CTRL and click and drag one of the arrows to move it to the side.
Create a new Post Processing Volume and put it on that new Plane

Also don't forget to put it on the Post Processing Layer!

Very important: If you want to use more than 1 volume, you cannot use Is Global tick button option. So they all must have that green box

Step 10

So let's check our two Post Processing volumes in Play mode!

Step 11

Next, let's just stick to one IsGlobal Volume, so we'll use the first one.

Step 12

Modern games actually use a Tonemapping setting called "ACES", so let's enable that!

Step 13

You can see right away that it has powerful contrast, has bold colors, and pale highlights!

Does this look awesome!?

But hold on, we're not done yet! We still got more to cover!

Step 14

Let's move onto Motion Blur!

What is Motion Blur?

In Photography, it's the shutter speed of our Camera. The higher the shutter speed the more on-point something looks, even if it's moving fast.

The slower the shutter speed, the more it looks like the image is dragging across the screen or canvas.

Step 15

But in Unity's Post Processing we use "Shutter Angle". Let's try it!

Add the motion blur, click "All" to enable it. And then leave everything as is for now.

Check Your Work

Step 16

Click play and start moving your camera around, you'll feel the difference!

While in Playmode, try adjusting the Shutter Angle to 0, and then back to a high number. You'll feel the difference, and then leave it at a number you think is good for you!

Step 17

Next effect we'll do is "Depth of Field"
