Shadow

In iClone all except the Point Light are capable of generating shadow.

Shadow Type

From the Shadow Type drop-down list, you may decide to set the shadow effect to None/Self-Cast Shadow/Drop Shadow/Wall Shadow:

None	Self-Cast Shadow (Directional Light)	Self-Cast Shadow (Spotlight)

The Shadow is turned off.	The Shadow is turned on with directional light.	A realistic way to calculate the physical projection of shadows from the light source via the shadow map technology. Cast and receive shadows both from characters and props/scene. Shadows can be cast on the source's own surface as well.

Drop Shadow	Wall Shadow

A quick way for objects to drop shadow Only on the virtual floor (X-Y plane) or 2D background but not on any other 3D objects.	Wall Shadow will create a 2D shadow effect by offsetting a shadow directly behind objects. If you select this option, the Offset X, Y will be enabled for you to define the position of the shadow. Please note that the Wall Shadow is cast merely on the 2D Background and Sky and not on the Terrain.

More about Self-cast Shadow

A higher resolution shadow map is required if you wish for all scene elements to cast shadows.
Self-cast shadows can only be projected on 3D objects but not on the virtual floor (X-Y plane) or 2D space.
If a self-cast shadow is cast on an object with alpha transparency effects, it might cause some artifacts.
Please refer to Self Cast Shadow Option for more information.

Shadow Opacity

Adjust the Opacity value to define the transparency of the shadow. In general, stronger light (especially directional lights) will cast higher opacity shadows.


Opacity = 60	Opacity = 100

Threshold

The Threshold sets decides the level of transparency that is required to cast shadows.


Object and its Opacity texture	Threshold = 30

Threshold = 50	Threshold = 70

Blur

Check the Blur box to enable this feature. Adjust the Blur Level to define the edge softness of shadows.


Blur Level = 1	Blur Level= 10
