If the curtain wall is any bigger than few hundred square meters, the export to render or to studio can take from minutes up to few hours, depending on the size of the curtain wall. Can somebody else confirm this?

It's not due to the number of elements, as if it is converted to morphs, it will start to render immediately. This is a workaround but not really a solution.
