Run this little script in After effects CS3 to export your AE camera path to Autodesk Maya, Lightwave or Max. I have only used it in Maya so far, but it works fantastic! Unfortunately though, I could NOT get the script to run in After Effects CS5, it crashes.
This script was graciously created by Ryan Gilmore (www.urbanspaceman.net)
In AE just go to file>scripts>run script file.
