I have revised the After Effects To Blender exporter to update it for Blender 270a api changes. See post #44 for caveats with this version.
As far as tracking and camera matching tasks, however, we are still in untested waters.
The concept behind this Adobe Javscript (.jsx included in the attached ZIP file) is like any other exporter. The exporter scans the host application for data and generates output in a different format. The format, in this case, is Blender 2.70a python.
Select the layers you want to export in your After Effects comp.
Click the export button and wait for python generation to complete.
Exit or Hide After Effects.
Locate the generated python script (many times it just appears on the desktop).
Open Blender 2.70a or better and load the generated python script into a text window.
Run the code in that window.
The code in the python script will attempt to construct a scene similar to the scene in After Effects.
FIXES For Alpha v1.0:
It now works in CS5 &CS6 (yeah!).
The correct FPS is being relayed to Blender from After Effects.
Text from After Effects appears as extruded font object inside Blender.
Footage layers appear as correctly sized planes with a material applied to them pointing to the footage.
Axis orientation for the whole Blender scene is rotated 90 degrees along the x-axis to match After Effects.
Lens default value more closely matches After Effects for a tighter Pixel-to-Pixel match.
FEATURE ATTEMPTS FOR ALPHA:
I am calling these attempts because the code is still in that state.
Full Camera Animation (need to test animating FOV, DOF, is aspect ratio right…?)
Solids are exported as animated empties.
Footage is exported as a plane with a material assigned to it that links the AE footage to the plane as a movie or image sequence texture. (Ambitious, but I think necessary to make this a one-shot wonder kind of script.)
Text layers from AE are converted to actual 3D font objects in Blender.
Lots of testing needs to be done.
I have tested it on a couple of scenes with CS5 and CS6 only. So further testing on creative cloud versions is needed.
