Well, I'm thinking of allowing designers to edit some parts of the level visually, and am looking for away to export the data into a useful format. Serialization isn't really all the usable as it's not guaranteed to work across versions, etc. So the exporting to XML or back to 3ds or whatever would be great. Actually, now that I think about it a way to export individual Object3D's would also be useful. But if there's a chance at just exporting the whole scene to XML that would be great. Thanks.
