128 Chapter 3 Depth Compositing
3 Expand the subtree beneath the L8 (sunsky) layer and set the camera distance value to
2500.
Note that this changes the position of the layer along the Z axis, but the camera lock
ensures that the view from the camera’s perspective does not change. In this case, it
allows the sunsky layer to appear behind everything else in the composite.
4 Adjust the camera distance for the other layers, to match these settings:
• L5_cameraDistance = 1500
• L4_cameraDistance = 1200
• L3_cameraDistance = 1000
• L2_cameraDistance =800
• L1_cameraDistance = 700
This takes care of the distance/position for each of the elements locked to the camera.
These are just arbitrary numbers to space the layers; on a real shot you’ll want to be
more precise. Now you need to adjust the still images that will be affected by the
camera move.
5 Now preview the results by rendering a Flipbook preview.
When you play back the Flipbook sequence, things look fine at frame 95, but the
composite breaks down before frame 155. The two still images are not positioned
correctly, and do not match the camera move.
It’s time to import the camera data from the 3D animation project to create the proper
perspective change for the 2D images.
