For years the integration of 3D in the post-processing pipeline has been dominated by commercials applications. Today there is an alternative that I think can compete with the "big guys". I just released the After Effects Exporter for Blender.
[...]The exporter, nicknamed AEE, is released as Open Source Software and I hope to have it included in the final release of Blender 2.5. While other solutions have been tried before, I believe this is the first time that Blender has such complete support for After Effects.
This program integrates in the File/Export menu of Blender and it allows you to export an entire animation from Blender to After Effects, including the camera, lights, 3D meshes, planes, all of which will create corresponding After Effects 3D solids, and footage. The Exporter even supports multiple passes.
Paolo has prepared a 20-minute video tutorial on how to use the exporter, and supplied a link to download the projects files, which includes the exporter, a Blender Python program, a manual, and the blender file shown in the tutorial.
(Also thank you to Mitch Klein for reporting that Creative Cow has just recently added a Blender forum!)
