Ambient Occlusion in Unity URP

The video tutorial introduces a feature in Unity 2020, ambient occlusion, which enhances game visuals by adding shadows to geometry, creating depth. It explains the differences between screen space and baked ambient occlusion, and how to implement it using the Universal Render Pipeline (URP). The tutorial also covers settings adjustments for performance optimization and concludes with the benefits of using ambient occlusion in game development.

What version of Unity reintroduced the ambient occlusion feature?

• Unity 2018

• Unity 2021

• Unity 2020

• Unity 2019

What is the primary visual effect of enabling ambient occlusion in a scene?

• Enhanced shadows and depth

• Sharper textures

• Increased brightness

• Faster rendering

In which Unity rendering pipeline version is ambient occlusion available as a renderer feature?

• URP version 10

• URP version 8

• URP version 11

• URP version 9

Where can you find the ambient occlusion setting in the Universal Render Pipeline?

• In the animation settings

• In the renderer features

• In the texture settings

• In the lighting settings

What is a key difference between screen space ambient occlusion and baked lighting?

• Screen space considers only what the camera sees

• Baked lighting works on dynamic objects

• Screen space works only on static objects

• Baked lighting is real-time

Which type of ambient occlusion is suitable for scenes with moving objects?

• Ray tracing

• Baked lighting

• Screen space ambient occlusion

• Global illumination

How can you improve performance when using ambient occlusion on low-end devices?

• Enable all post-processing effects

• Downsample the effect

• Use higher resolution textures

• Increase the sample count

What is a benefit of ambient occlusion being a renderer feature in URP?

• It works independently of the volume system

• It enhances audio effects

• It requires less memory

• It automatically adjusts to lighting changes

What is the effect of disabling post-processing while using ambient occlusion in URP?

• Textures become sharper

• Ambient occlusion is disabled

• Ambient occlusion remains active

• The scene becomes brighter

Why is ambient occlusion considered beneficial for most scenes?

• It increases the frame rate

• It adds a sense of depth and realism

• It reduces the file size

• It simplifies the lighting setup
