Creating the castle

I firstly tried constructing the wall from individual bricks using the Array tool but after 3DS Max crashing three times in a row I thought it best to use simpler shapes.

I created the wall by using basic boxes and then excuding the polygons in the editable poly menu.
Also from here I could highlight other "bricks" and put random notches and bumps to give the effect of a damaged wall.

I bevelled a window shape into the wall to create the window shape.

Here is the castle before material rendering.
