Shaders and Materials

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

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.

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

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

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

It’s common to import a material that was originally made for a shader that isn’t present in the current project.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

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

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

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

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

What is a mesh? Select one answer.

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

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

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.

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

Diffuse map, base map, and albedo.

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

Input nodes that users of the shader can configure in materials(?)

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

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

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