I’ve found that by the time I render out each template blank, then the phone numbers, and the comped spot combining the two, I’d be back at around 20-min./spot, which is where I am at the top of this thread…
I did learn MUCH about capabilities and limitations in this exercise. I also poked around with the recursive number, finding that I needed it set to 2 bounces to allow the effects desired.
Thanks again for your collective wisdom!
