This project actually bit bigger than just one piece of ceiling. This is true i used Rhino for straight geometry but it's only because in the project i'm must repeat exactly the cad model and Rhino is the only program that is the CAD and polygonal in the same time.
I can imagine how to do this entirely in Zbrush but in this case i'll be done this job twice first the cad model and then polygonal model.
The first image which started the topic was done partly in ZBrush, i've done there the hi poly model for the baking texture, color map and etc. I just remeshed the CAD model, painted it add some flaws, wrinkle smoothed corner.
