How to load a animated prefab from AssetBundle properly

Hi there,

Let me explain you my problem :
I have an animated prefab using an existing fbx file containing the model and the animation (from Blender) and an animator controller in charge of handling the animations.
The problem is that when I export this prefab in an AssetBundle, I am not able to load it.
It is for an augmented reality app for Android using Vuforia. This is the only animated model (it is for test for now) and the other models which are not animated - so not prefab but just fbx files - load without any problem.
I am using the WWW method for loading the assets from the AssetBundle.
I tried by changing the name of the fbx file so it does not have the same name as the prefab to avoid name conflicts but still I got this problem …
Please help me

Thank you guys
