Which is better: a wall with many windows or many blocks with one window each?

Question

3D rendering

What is best to use in Unity3D: one block of a wall with many openings for windows or a wall consisting of many blocks, each block has one opening for a window?

Answer 1

is the wall destructible/dynamic?
and it is necessary to consider collisions and do not want to arrange handles?
better in terms of the convenience of a game designer / level designer? Or in terms of performance?
If it will be static from one material, then at least from a bunch of pieces, at least from one.
It is more convenient to make different shapes from blocks.
Plus, if some kind of Occlusion - then the blocks can partially not draw what does not fall into the frame.
in general, you have a very abstract question divorced from reality))
I hope that by answering my questions for myself, it will become clearer what you need.
and in general, in the end, in fact, it’s all the same in the application, just look and profile in order to understand how and where it’s better to do it)

Answer 2

The essence of the question is what is better to render - a bunch of thin and long polygons, which are obtained if there are a lot of windows on one wall, or about the same bunch of short polygons that are obtained by placing a single window on rectangular blocks from which the wall is composed. The surface area is the same.
