The planet Coruscant (both the planet from space and the buildings on the "surface") and all of its space traffic and skylanes were created and animated in 3D Studio MAX. Deak Ross' ship was also a three-dimensional component of those shots. The droid M3NO and the hologram in Yanic's shop were also created and animated three-dimesnsionally. Many lower and mid-level aspects of Coruscant, such as the turbolifts and hovertrain are also examples of 3D animation.
Many fill-in shots or entire sequences were filmed in front of a bluescreen. They were then captured and brought into Adobe After Effects to be keyed. They were placed in the background and the final shot was created.
A lot of the aspects from shots on real world sets were added in digitally in Adobe After Effects. This can be seen most prominently in Yanic's shop and the streets of Coruscant.
In order to put in any digital additions effectively, a lot of masking and rotosplining had to be done in Adobe After Effects. All the windows resulted from masks on the footage layer, as well as when any actors would need to walk in front of any digital additions. In the streets of Coruscant, masking was used in correspondence with a control camera, which was used to film the same extras many times in different costumes.
The hologram in Yanic's shop was first rendered in 3D Studio Max, and then additional components were added in to complete the effect in Adobe After Effects, such as footage of interference from a monitor refreshing used as a luma matte. The composition was then inserted into the footage.
The blaster bolts coming from blasters were made in Adobe Photoshop and then added into the necessary shots in Adobe After Effects. One picture was created and then distorted to produce a perspective effect.
To add the explosions during the blaster fight, footage was acquired of explosions on black screens. It was then placed over the object that the blaster bolt was hitting in After Effects.
The steam venting down violently from a lower level ceiling was first rendered as a single glowing particle system in 3D Studio Max. It was placed in multiple times and blurred in Adobe After Effects. A movie of smoke billowing from the ground added the final touch.
