Thank you CarlG. This was in 2.79 that it happened. Here is a
new render. Let me know how I can improve it. I modeled the tiles in 3d with Mark Kingsnorth’s plating and greebles generator. A while back I used the addon to model the rounded tiles for a large arched window. Works great. See the last post here. Tissue by Alessandro Zomparelli - #304 by bkjernisted
