After (3 Polygonal Morph Tool) Tube Extrusions
The morph tool is used to create complex polygonal shapes. Having one slab using the morph tool prevents some texture overlapping issues I was having trying to cover the little nooks and detailed areas. I was having trouble with selecting objects until I discovered the Suspend Groups option and the hotkey Ctrl+L to show or hide layers, which saved me a lot of hassle in selecting slabs, walls, and objects.
