Model with large windows - do I need to give them a depth value


I am planning to do a model with large windows, model will be 9m high by 50m long, do I need to give the windows in the model, which are 3m, by 1.5m a depth value such as 15mm, for renedering purposes in either photoshop or enscape?


If they have different materials applied to them as compared to the surrounding wall, they will show but may look more like large rectangles painted a different color. If you want to render shadows, you would need to push them in a bit. If you are adding shadows manually, it probably doesn’t matter.
