In this quiz, you will assess your knowledge of VFX, including the Unity’s Particle System and VFX Graph.

Languages available:

Question 1

What is the best description of how a particle system works in Unity? Select one answer.

Select only one

A particle system breaks down a complex mesh into its component vertices to simulate many moving parts and produce a visual effect.

A particle system renders many small images or meshes, called particles, to produce a visual effect.

A particle system shoots light through a complex lens, similar to a projector, to produce a visual effect.

A particle system generates individual pixels of varying sizes, each with a different material, to produce a visual effect.

Question 2

In the main module of the Particle System component, what does the Start Lifetime property determine? Select one answer.

Select only one

How many seconds an individual particle will exist before it disappears

How many seconds the entire particle system will exist before it stops emitting particles

How many frames it takes for an individual particle to fade in to the scene

How many frames the delay is before the particle system begins emitting particles

Question 3

In the Particle System component, what does the Shape module control? Select one answer.

Select only one

The shape of an individual particle.

The volume that particles within a system can exist in – when particles leave this shape, they disappear.

The shape of the collider that particles cannot enter – if particles collide with this shape, they disappear.

The shape of the volume that is emitting particles – particles can only be spawned within the defined shape.

Question 4

You’re trying to make a particle system that produces a steady stream of particles. However, you notice that there are large gaps in the emission of particles (see image below). What could be done to resolve these gaps? Select all answers that apply.

Select all correct answers

Decrease the Start Lifetime

Increase the Start Speed

Decrease the Rate Over Time

Increase the Max Particles.

Question 5

To change the default particle system, which emits a constant stream of particles, into a single burst of particles, what would you do? Select one answer.

Select only one

Disable the Looping property

Reduce the Max Particles

Enable the Stop Action property

Enable the Limit Velocity over Lifetime property

Question 6

How can you tell if a particle has been created with VFX Graph rather than with the Particle System? Select one answer.

Select only one

If the particles have noise, they were created using VFX Graph, since the Particle System does not support noise

If the individual particles are 3D meshes, they were created using VFX Graph, since the Particle System only supports 2D textures.

If the particles have any elements of transparency, they were created using VFX Graph, since the Particle System does not support transparency.

If you double-click on a VFX Graph object in the Project window, it will open in the VFX Graph window.

Question 7

Which of the following are true about the differences between VFX Graph and the Particle System? Select all answers that apply.

Select all correct answers

VFX Graph supports a higher particle count than the Particle System.

VFX Graph runs on the CPU, while the Particle system runs on the GPU.

The Particle System uses Unity’s underlying physics system, allowing particles to interact with other physics-based objects in the scene.

Even though the Particle System is a bit simpler to use, VFX Graph is capable of producing more complex simulations and allows for more customizable behaviors.

Question 8

Which of the following is the correct order of contexts in a default VFX Graph? Select one answer.

Select only one

Initialize > Spawn > Update > Render

Spawn > Initialize > Update > Output

Instantiate > Spawn > Behavior > Render

Spawn > Behavior > Update > Output

Question 9

To edit the equivalent of a Particle System’s Start Lifetime in a VFX Graph, in which context would you look? Select one answer.

Select only one

Initialize

Spawn

Update

Render
