Rendering is all over the place.

I noticed when rendering my 3D in photoshop, that my 3D extrusion has another smaller copy of he same image "skinned" onto it which is destroying the very graphics I am trying to make. This is getting very annoying considering that up to only yesterday the geniuses at Adobe had set the infinite lights to such a position where they were "reversed" and unusable, but now rendering is all over the place. I can tell you thank god Adobe has competition because I really cannot use this bloody software anymore, it's little more now than over-priced rubbish! I haven't been able to properly use this software now for over six months because it's been one bug after another and I frankly feel Adobe are just fleecing my pocket now at this point.Can ANYONE explain to me why this is happening because this wasn't happening before yesterdays disaster of an update.
