Describe the bug

It appears that, when you place a fluix cable and surround it on all six sides with facades, the internal model elements- the cables, backsides of the facades and the metal bits attaching them to the cable- all still render. I think it would be a good optimization for the client to have these faces be invisible in this case, so the whole block renders like a normal block.

How to reproduce the bug

• Place fluix cable
• Attach facade to all six sides
• Enter spectator mode
• Clip into the block
• Observe inner elements rendering

Expected behavior

The cable would not render its internal faces when they are all obscured.

N/A, not a crash

I doubt such an optimization would make a difference in practice, and I generally dislike premature optimizations, i.e. optimizations that are not motivated by a performance report. Cable rendering is already quite efficient.
