Motion Blurred Shadowmaps

Options: Ambient Occlusion [Properties Reference]

Select the Shadowmaps Motion Blur checkmark to activate the shadow mapping option for motion blur effects. Shadow maps are a scanline-based feature that produce shadows faster than raytracing. Activating them with motion blur slows render times but matches the shadow to the motion blur nicely. If you are running a quick render test, keep this option off.
