Getting Unity Studio to export .fbx with skinning

[Ecelon]

I'm using the latest version of Unity Studio, and while it works good for the most part, sometimes the model I export to fbx won't preserve the skinning . I've tried a lot of methods in order to get the  models with their skinning in-tact, and like I said, it won't work sometimes. Am I the only one experiencing this, or is it just a bug with Unity Studio as a whole?

I want to rip models from Angry Birds Action!, in case anyone's wondering. It's Unity powered, so I'd like to use Unity Studio on it in order to rip the models WITH their skinning in-tact. Is there any other Unity model ripping tools that can rip models while preserving the rig and bones?

So far, only Unity Studio extracts with Bones and weights. Your other option is Disunity. It'll extract as .obj but you'd have the uv maps in place.
