Technical Details
This system provides:
3 Styles, each style has multiple sections, Ground, Mezzanine, Trim, Window, Roof. Each has its own variation. Some more than others.
4 Window styles are provided. Each style has variations ( up to 8 )
6 pattern profiles are provided. They are used interchangeably with all style. Each facade creates even more variation by using these pattern as 'skins' to the original building facade.

As with all of AmmoboxStudios's system as well. Performance is a high consideration as we are using this for our internal development as well.

Here are some optimizations:
( remember that when it comes to optimization , less means more )
1) All windows are instanced per style, per entire row.
2) Each Facade style is represented by a 1 ( Single ) material iD only. If entire row uses a single style this means it's only using a single 'set' of textures.
3) All Window style used one set of texture. Variation is panned using Per-Instance Data.
4) All styles are equipped with LOD for the individual section meshes.
5) Pattern profile uses 2048 sets that is shared across all style.
