Section I: Making the Map Image

1. It’s usually a good idea to start with a sketch of what it is you intend
to do, marking out where buildings, roads and other key features will roughly
be positioned. Even better would be to use an aerial photo which looks straight
down onto the area you plan to recreate (these, however, are pretty hard to come by).

2. Create your map image using a paint program such as Paint Shop Pro or,
if you’re exceedingly wealthy, Photoshop . The map size should be in multiples
of 120 pixels and no larger than 2880 x 2040, which is the largest size CC3
recognizes. Save the file as an uncompressed TGA file. A good starting point
for graphic elements on your new map are existing maps. You can get these by
converting your original CC3 maps (ie the mapname.BGM files found in your CC3Maps folder)
by using the method and tools described below in the “Texture Maker” section.

Section II: Making the Roofs and Interiors

3. To create the exterior roof image, use the selection tool in your paint
program and marquee the entire roof including any landscape outside the building
as necessary to fit the entire roof inside the selection area. Buildings
flush with the map edges (ie. at right angles to the edges) should have 1-2
pixels of landscape included with the roof selection. Buildings angled (ie. not
flush) will have as much exterior landscape included in the selection as
necessary. It is Important that you make no changes to the landscape, including
adding shadows, once you select and copy your roofs. At the point you select
each roof to copy, note the corner pixel coordinates of the upper left and
lower right corners (X1 and Y1). Keep a running list by naming each roof you
copy (eg, ext1.TGA) including the coordinates.

4. Image coordinates MUST be accurate. If not, you will end up with a skewed
roof/interior image on your map. The most accurate way of determining the correct
coordinates is to note the X1, Y1 coordinates and add the image dimensions to this
(use the view image information feature of your paint program to get this). This
will give you the correct X2 and Y2 coordinates.

5. The way roofs work is that you view the .BGM map until teams enter the boundary
defined by the corner coordinates of each building. When they do, the game imposes
the interior image which you will create from a copy of the copy of the roof. When
teams exit the boundaries of each building, the game doesn’t revert back to the .BGM but
imposes the roof image you have copied. This is so that if there are dead
soldier sprites in the building they will be 'covered' by the roof image.
Otherwise, if the game reverted to the .BGM these dead men would suddenly be on
top of the roof.

6. To create the interior images, make a copy of the roof copy made above
(roof and interior images MUST be the same size) and 'hollow out' the interior
by creating walls (~4 pixels wide) and adding a floor texture or color. Larger
interiors can include furniture and inner walls if you wish. Be as creative as
you like when doing interiors. Name your finished interior image (eg Int1.TGA, etc)
and place the roof and interior image 'pairs' in a folder. I prefer separate
folders for the interior and exterior images.

7. Use Texture Maker 3 to convert the image pairs from .TGA to CC3 format.

8. To create the .RFM (roof), file, use Dreaded88's Roof Maker.
It’s very straightforward (see next paragraph). Run Roof Maker from the directory
where you have your CC3-converted roof pair images. The program will generate a
"map.RFM" file in the directory it's run from. Rename this and copy
to the maps folder in your CC3 directory when done. Make sure the file name
is the same as the other files for your map and is not longer than seven
characters, otherwise CC3 will not recognize it.

9. After executing the Roof Maker program, you will be prompted for the following:
