I am a Crysis map maker, taking my first crack a the hammer editor. Mostly because I love playing Left4Dead.
With the release of the SDK and SketchUp tools I think I can get started on a map idea I have had floating around, as I am already pretty good in SketchUp.
My popular Crysis map: Castaway, and several others are all based on real-world locations. Typically done at 1:1 scale. This campaign is no different.
The map location is the "Trans-Allegheny Lunatic Asylum" formally known as the "Weston State Hospital". The place was built in 1864 and operated for 130 years. The perfect location in my mind for a zombie apocalypse. The Asylum sits in the Allegheny mountains, hence the name. It is about 250 miles from the Allegheny National Forest in which Blood Harvest takes place.
Here is a link to the area on Google Maps:

Right now I am learning the editor, modeling my building in SketchUp. I have literally hundreds of reference photos to work off of.
This will be a five map campaign with two maps located mostly outside, three mostly inside.
-----------------------------------------------------------------------
The following is some of my initial work in inside SketchUp:

My first step in making this series to layout the overall map.
I opened up SketchUp and imported a satellite photo of the asylum.
All the buildings are placed exactly where they are in real-life.
All of them are to approximate scale using the shadows in the photo as height reference.
This step is simply to get a feel for the overall scale, and how I can split the map up into 5 pieces.
Part of this will also become the 3D mini-map background.
Currently the map will start near the water tower on a hill (Cylinder near the top)
The survivors will go from there into some of the back buildngs, before entering the actual Asylum.
The middle maps will take place mostly in the asylum, with open areas such as a burned out roof, and some court yards. They will progress all the way to the medical building, which is at the bottom left of the image. From there the final map will take place mostly outside in front of the asylum, with the climax happening inside the main hallway of the asylum. Escape will be tough with a run across the open ground in front, towards a bridge that crosses a river.

Obviously the map doesn't look like much in-game. But to give a sense of scale, there is a tank near the aiming reticle that looks like a smudge on the large view screenshot. Keep in mind this area will be split into five parts.
-----------------------------------------------------------------------
Here is the first bits of modeling.
I am working on the building in the bottom left of the map, and the background building for my poster. SketchUp has a great photo-match feature, that allows me to use reference photographs to help model the building accurately. The model will be built up using normal SketchUp techniques, then re-textured, broken into chunks for in-game use.

Once this model is complete I will work out the best way to export it into the Hammer editor. Once complete I can start on the actual asylum, which is much larger, but has a lot of repeating components.

Here is a photo of the real building:

Here is the model completed and rendered in-game.
I have all the components to the tuberculosis ward in the game.
The model is made up of lots of static_props. Broken apart so ensure the game can cut the leaves properly. These models have proper physics and will work best as background buildings. The model is also the template for the full brush objects to be built around, allowing for the survivors to enter the building and have interior spaces.
If anyone missed it, despite the poster image, this ISN'T the massive asylum. This is just one of the side buildings. I like the new brick texture, and the rest of the components turned out nicely.






















































Good Work, Crow!
