Dennis Ippel, one of the Sandy3D developers, just released his Blender export script. for Sandy3D, but also Away3D and Papervision 1.7.

Check it here and let your comments there!

This Blender (free 3D modelisation tool) export script is a possibility to generate native 3D objects (no parsing required), as the Seraf AS3 geom exporter is doing with 3DS Max .

Good job Dennis!
