-# Shadow Controls
-
-Two light attributes, `max_shadow_distance` and `clear_radius`, define constraints on how shadows can be cast from the 
-associated light. Both of these attributes work in tandem to define the region where shadows cast by the light can appear. 
-
-## Max Shadow Distance
-Limits shadows cast by the associated light to *max_shadow_distance* away from the shadow caster. In the example below, 
-the shadow's distance from the shadow caster (the plane) ranges from 5.7 to 6.4.

-    </video>
-</figure>
-
-## Clear Radius
-Ignore shadows cast by the associated light until *clear_radius* distance is reached. We can think of this as the 
-minimum distance away from the light that shadows can appear. In the example below, the shadow cast by the plane is 
-between about 48 and 54 units from the light.

-    </video>
-</figure>
-
-## Combined Behavior
-*clear_radius* should always be less than *max_shadow_distance*. If *clear_radius* overlaps *max_shadow_distance*, no shadows 
-will appear. In the example below, you will see this behavior, as *max_shadow_distance* stays the same (at 6.1) and the *clear_radius* varies.
