1. Can anyone explain what is "Set Fog Linear/Expo1/Expo2, z-start #, z-end # 2. How do i change water titing colour slowly from blue to black? Thanks to whoever that helps me with a complete answer. |

Not sure about water tinting color, but here's the deal with the fog: Z-based fog is a rendering method that "fades" polygons that are further away from the camera. The parameters for it control the following: Linear/Expo1/Expo2 in theory controls the ramp of the fogging: in a linear ramp, the change in fog density is directly proportional to the distance from the camera source; theoretically in an exponential ramp the change would vary with some power of the distance from the camera source, but I've never noticed any difference between linear and exponentials, so this might not be the way it works. Z-start is the distance from the camera where the game "starts" fogging polygons. If you set Z-start to 3000, for instance, all polygons within 3000 units of the camera will be unaffected by fog. Z-end is the distance from the camera where the game "finishes" fogging polygons. If the Z-end is 5000, all polygons at and beyond 5000 units from the camera will be completely fogged - that is, solidly colored whatever color you set for the fog. |
