Recently I've found that AWDs generated from prefab have certain parts of a model flipped on various axises when opening in away3d lite. The same AWD re-opened in Prefab looks fine.
Here is the awd I'm using (i know its huge): http://dev.aliencom.net/away3d/model5.zip Previously I've had no issues with prefabs AWDs in away3d lite, but it seemed to happen suddenly on this model. Fortunatly the Prefab export as away3d class still works fine.
