but the bigger problem is that the windows are placed verticaly on 2 segments and horizontaly on the other 4 segments. to this problem i couldnt find a solution. how to rotate the placing of windows in a curtain system 90 degrees?
I don't have an answer but I was wondering if I could ask you a question. How did you get your mullions and glass to curve along your curtain grid. When I create a curtain grid from mass face my curtain panels and mullions are always straight (like the grid on the left in your image).
