My last ditch attempt rendering the problematic frames of shots 5 and 6 worked. I’m a bit embarrassed that I didn’t put together that most of the successful frames came from the render nodes and not the Monty machine nodes, but at least it happened before it was truly and entirely too late.

Here is the tower, in it’s final version (for now, because going back to fix up old projects is one of my goals for continuing to learn after graduation).
