Preview Shadows

ObjShadow: Controls the intensity of the model's real-time shadows.

BackShadow: Acts as a drop shadow cast by the current model and projected onto the canvas. The slider value controls the intensity of the shadow.

Length: Increases the scan range that ZBrush uses to create the shadow. A larger Length will lengthen and soften the shadow but will also increase computation time.

Slope: Sets the azimuth of the light used to project the shadow. All shadows fall at a 45 degree angle across the canvas. This cannot be altered. Slope controls the angle in Y at which the light casts the shadows. Zero means that the light is directly overhead of the model. A larger number means that the light is more in front of the model.

Depth: Deepens and enlarges the shadows. The effect of Depth depends on the setting for Slope; at small settings of Slope, changing Depth will have little effect.
