Creative Core: Shaders and materials quiz thumbnail

In this quiz, you will assess your knowledge of shaders and materials, including the use of Shader Graph.

Question 1

What is the difference between a shader and a material? Select one answer.

Select only one

A shader is a script that runs as part of the rendering process, and a material is an asset that specifies properties to a shader.

A shader is used in physically-based rendering to create photorealistic effects, and a material is used to increase performance if photorealism is not necessary.

A shader affects how light appears on an object, and a material affects its color.

They are actually the same thing.

Question 2

What is the difference between a lit shader and an unlit shader? Select one answer.

Select only one

A lit shader allows you to add emissive light to an object, so that it can appear to light up. An unlit shader does not, but using unlit shaders increases performance.

A lit shader only works with the Universal Render Pipeline. Other render pipelines use unlit shaders.

A lit shader adds shadows and reflections according to the light that reaches the object. An unlit shader ignores the effects of light.

None of the above.

Question 3

Why do materials sometimes appear bright magenta (pink) in the Unity Editor? Select one answer.

Select only one

It’s common to import a material that was originally made for a shader that isn’t present in the current project. To fix, specify a shader that is in the project.

Materials appear pink if they are missing a base map or color. To fix, add a color.

A material created for one GameObject can’t be applied to another without being configured properly. To fix, adjust the material for each new GameObject.

A pink material indicates an error in the shader script. To fix, correct the error or select a different shader.

Question 4

What are two ways to make an object look metallic using the URP/Lit Shader? Select one answer.

Select only one

By using the Specular workflow or the Metallic workflow in a material.

By applying a diffuse map or a metallic map.

By applying a diffuse map and a normal map, or a specular map and a height map.

By using a specular shader or a metallic shader.

Question 5

What is physically based rendering (PBR)? Select one answer.

Select only one

Rendering using shaders that most closely simulate the real-world behavior and properties of light.

Rendering in 3D using materials designed to look like real objects.

Rendering that uses normal maps and height maps to simulate physical variations on a mesh.

Rendering that uses a combination of vertex and fragment shaders to achieve realistic results.

Question 6

What is a mesh? Select one answer.

Select only one

The geometric data of a GameObject, consisting of vertices, edges and normals that define the shape of an object in Unity.

A data structure used only for organizing audio sources in a scene.

A component that defines the way light reflects on it.

The texture format used for applying materials to objects.

Question 7

What is the difference between a normal map and a height map? Select one answer.

Select only one

A normal map specifies the direction that a surface is facing at a given point, and a height map specifies how high from the mesh surface to raise the rendered surface.

A normal map contains the data of the basic mesh before rendering, and the height map specifies how high from the normal surface to raise the rendered surface.

A normal map specifies the normal color to render the mesh, and the height map specifies how high the reflectivity of the surface will be rendered.

A normal map specifies the normal properties of the surface, and the height map specifies how those properties change depending on the distance of the surface from the viewer.

Question 8

Which terms are used in shaders and materials to refer to the color of an object? Select one answer.

Select only one

Diffuse map, base map, and albedo.

Diffuse map and specular map, and metallic map

Base map, normal map, and albedo

Base map, normal map, and specular map

Question 9

In Shader Graph, what items are listed in the Blackboard? Select one answer.

Select only one

Input nodes that users of the shader can configure in materials

All nodes used in the current graph

Nodes that can be added to the graph

Nodes not yet connected to the graph flow

Question 10

In Shader Graph, what is the Master Stack? Select one answer.

Select only one

The list of end nodes for vertex and fragment shading, which provides an end point for the graph

The list of all nodes used in the shader

The list of all nodes available to be used in the shader

The start point of the graph

Question 11

What is a method of applying a material to a GameObject in the Unity Editor? Select one answer.

Select only one

Drag the material from the Project window to the GameObject in the Scene view

Select the material from the Mesh Renderer component

Drag the material from the Project window to one of the Materials listed in the Mesh Renderer

All of the above

None of the above
