3D renderingCompositing the 3D information in After Effects requires different algorithms than those needed for rendering 2D information. After Effects provides a 3D renderer that computes the motion blur, lighting, shadow, and depth-of-field information unique to 3D. The 3D rendering order differs from that of 2D. In the standard rendering order, After Effects renders layers according to their Timeline order, from the bottom layer to the top layer. In contrast, the 3D renderer calculates 3D layers according to their spatial order in the Composition window, from the most distant layer, or the one with the highest Z coordinate value, to the closest layer, or the one with the lowest Z coordinate value. If compositions contain both 2D and 3D layers, then the rendering order becomes more complex. See Rendering compositions containing both 2D and 3D layers for more information on how After Effects handles rendering such compositions. After Effects renders the X, Y, and Z rotation Transform properties in their descending Timeline order, regardless of the original order in which you set those Transform properties. Note: After Effects does not render intersecting layers. Related Subtopics: |
