alpha problems with Photoshop 3d and AE

Hello all,
I am using Photoshop 3D elements in an After Effects 3D comp. The elements work as intended in the comp, but when i export (QT Animation RGB+alpha) the Photoshop 3D elements do not maintain their transparency.

Any ideas on how to maintain the alpha channel from the Photoshop PSD files?

Thanks,
John
