In the Inspector, the HUD, or the Canvas

Question 4

What’s the difference between layers in a 2D group and in a 3D group?

Answer 4

Layers in 2D groups are not affected by the camera, and are composited based on stacking order in the Layers tab.

Question 5

Do the 3D View tools always control the camera?

Question 8

In the HUD, how would you set the Adjust Around pop-up menu if you wanted the z-axis of a layer to always point straight at you, no matter how the layer or the camera was oriented?

Answer 8

Set the Adjust Around pop-up menu to View Axis mode to orient the axes so that they reflect the orientation of your computer screen.

Question 9

If you applied an image mask to a layer that is positioned in 3D space, why wouldn’t the image mask appear on the layer?

The image mask source is not aligned to the layer you are masking.
