Normally, if you create an effect with multiple DVE layers, each layer is rendered separately. The layer that is topmost in the timeline overlaps all other layers, no matter how the layers move or rotate. The BCC Z Space filter allow you to create effects using multiple DVE layers (“Z planes”) and/or sphere layers which can interact and intersect in 3D space. In a Z Space effect, each plane or sphere’s apparent depth, or position on the Z axis, determines how the plane interacts with other planes and spheres. The plane closest to the viewer in Z space covers planes and spheres that are farther away, regardless of the order in the timeline.
