# Compiling And Iteration

## Compiling

Using Compile Tools

Inside call of duty/bin/,(thanks to Chad G.) there is an exe that is an interface with the compiler. Use this application instead of the command line to iterate.

The first section on the left is a list of your maps.

The next section in the middle at the top is where you set your options for compiling the geometry and light map resolution.

The section in the bottom middle is where you set your lighting options.

## Iteration

Iterating on your maps can be a very slow process when it comes to lighting.

You can speed this up somewhat by using lower quality settings.

The first thing you can do is set the samplescale to higher numbers for a lower light map resolution. The default is 1.

The other thing you can do is use fast in the lighting section.

After you have tweaked your map enough, you can then use default samplescale and set the lighting section to extra.

Using modelshadows may slow things down, but I have not noticed any big difference in render times.
