A Normal Map is used to add surface detail to meshes without adding complex geometry.

• True

• False

Which two properties are used to manipulate the reflectivity of the Standard Surface Shader material?

• Reflectiveness and Specularity

• Hue and Saturation

What does the Drag property of the Rigidbody component control?

• How much air resistance affects the movement of an object

• 
  The quantity of matter in that object.

• Whether the object is affected by gravity.

• How much air resistance affects the rotation of an object.

Which type of Collider can be marked Convex to generate a closer approximation of an object's shape?

• MeshCollider

• Physics Surface

• Surface Material

• Physic Material

• Collision Surface

If two objects collide and one has a Bounciness of 1 and the other has a Bounciness of 0 but these objects are using Bounce Combine: Average, what will be the resulting Bounciness value applied to each object?

• 1

• 0

• 0.5

• 0.25

What is the term used to refer to a single object with multiple colliders?

• A single object cannot have multiple colliders

• Compound Colliders

• Multiple Colliders

What does the alpha value of a color control?

• The order of that color on the color wheel

• The saturation of that color

• The saturation of that color

• The opacity of that color

Which Rigidbody property would we use to stop a Rigidbody from rotating on a specific axis?

• Stop Rotation

• 
  Lock Rotation
