Don't like fire? Frightened by the cold darkness of outer space? Sea&Sky can help! The Sea&Sky Physics Model and textures replace Marathon's deadly lava & radiation pits with clear sparkling mountain water, and replace the inky blackness of space with a cloudy blue sky!
You'll need one of the various shape installers to use the WaterWorld textures. The two I'm most familiar with are Kevin Bell's "Marathon Shape Installer" and Joe Kloss' "Marathon Shapes Editor". Unfortunately, they use different numbering systems to reference particular shapes. The names of WaterWorld's texture files include numbers for both of these systems. The numbers on the left side of each file name represent the "Marathon Shapes Editor", the numbers on the right the "Marathon Shape Installer".
