100% is ok
btw, it happened again...exact same frame, exact same location.  Its where the camera crosses the infinite plane of the clouds...ie, they are on the same plane (camera and cloud).  Im wondering if the math for that portion is not causing a problem (two infinites in the same place)

I was going to let it run to see if it would eventually either error out or go on, but my power went out about 10 minutes after it hit that spot.  Sooooo..back to the drawing board (again)

sigh
