Ambient Occlusion Shadows: This function adds shadows to objects that are near each other, resulting in a crisper, more filled-out image that does not appear “flat”.
To Enable Ambient Occlusion Shadows:
1.In the Render Styles tab, under the Advanced Illumination, click Enable to turn on Ambient Occlusion.
2.Shadow Range: Represents the distance from the object that the shadow calculations include. For example, if a chair next to a wall is producing an undesirable shadow, the range can be reduced until the ideal shadow is cast. Recommended distance is between 12 and 64.
3.Quality Samples: Represents the number of samples that ICErender uses to calculate the shadows between objects. A low amount may result in more grainy shadows, but a quicker rendering time, and vice versa. Recommended value: between 32 and 128.
