Challenge: Create a local volume

1. Overview

Up to this point, you have been using a Global Volume to apply post-processing, which affects the entire scene. In this challenge, you will use a Local Volume to apply post-processing effects to a defined local area of the scene.

2. Why use a Local Volume?

A Local Volume can be helpful if you want the visual style of a scene to change when the user enters a particular physical space.

In a video game, you might make the scene a bit more dark and ominous when a boss battle is going to begin. Or you could apply some lens distortion and motion blur to indicate that the player has entered a toxic area that is making them woozy or nauseous.

3. Review: How does a Local Volume work?

When you use a Global Volume, post-processing effects will apply to a camera, no matter where it is in the scene. You have only used global volumes up to this point.

A Local Volume, on the other hand, is a defined smaller area within your scene. Post-processing effects will only apply when a camera is inside that defined area.

4. Add a local volume to the gallery scene

Here’s your challenge:

In the indoor gallery scene, add a local volume around one of the objects in the gallery, changing the post-processing profile as the user approaches it.

For example, when complete, it might look like the example below, where the blue cube artifact seems to have a mysterious and powerful aura around it.

Since this is a challenge, you will not be given step-by-step instructions here. For help figuring out how to do this, you can refer to Unity’s documentation on volumes or do some Googling.

You should expect to spend at least 30 minutes on this challenge.

5. Challenge criteria

You’ll know you’re successful if you’ve met these criteria:

• The post-processing profile changes when you approach one of the objects in the gallery.

• The post-processing effect gradually changes over the course of a few meters.
