Drop Shadows

A drop shadow, by default, is a dark, translucent, offset shape that falls behind an object,

as if a light was shining on the object. Drop shadows are the same size as the object to

which they’re applied, although blurring a drop shadow may enlarge it somewhat.

They create the illusion of depth, with the result that the foreground object seems to

pop out at the viewer. For this reason, drop shadows are frequently used to create the

impression of space between two overlapping objects.

Drop shadows also darken overlapping regions of background objects. A good example

of when to use this is when you place text over a background that might obscure it. By

adding a drop shadow, you can make a foreground text object easier to read.

Without a drop shadow With a drop shadow

It’s easy to add a drop shadow to any object, since each object has individual drop shadow

parameters in the Inspector and HUD. Once activated, drop shadows can also be

manipulated directly in the Canvas.

Tip: Motion also has the ability to generate true cast shadows when using lighting in 3D

layers. For more information about cast shadows, see Shadows.
