Wire-frames being rendered inside transparent objects Im sure it's probably a render option I need to turn on or off but I have an animation where we see a crane moving a sign.  As the sign comes closer to the camera, the crane disappears.  I keyframed the material to be transparent and also keyframed the eye ball (viewport visibility).  Most of the objects fade out but these black wireframes are left behind. When I switch to Render Viewport nothing is there but when I actually render, the wireframes are present. 
Any ideas?
Not sure I completely understand, but if you want to hide items from the renderer you need to click on the little camera icon (hides in render), not the little eye icon (hides in viewport).
