no in a new map the water is non-trans by default.....there is a option or something along those lines that makes it trans like in most maps...only thing is I dont know what that is :P
Water in maps is transparent by default providing that the video card settings provided can cope with the medium/high settings. Water transparency depths can be edited in the ini files and distributed with the map, in the same folder as the map toa void conflicts with the default settings - you can even change to color very easily!
its easy to do m8 you must make an ini file in the map dir called MAP.INI
then you do this
WaterTransparency
TransparentWaterMinOpacity = 0.6 ;opacity of water at maximum depth - 1.0 is opaque, 0 transparent.
TransparentWaterDepth = 5.0 ;depth below water surface at which it becomes opaque (unless clipped by TransparentWaterMinOpacity)
StandingWaterColor = R:207 G:240 B:243 ;material color used to tint the water surface.
StandingWaterTexture = TWWater01.tga ; main texture used for water (usually something blue that looks like water).
AdditiveBlending = YES; use additive blending instead of alpha blending?
RadarWaterColor = R:207 G:240 B:243 ; color of water on radar display.
NP this will help you out for good i use it to for some snow maps if the color is to bright just set the colors back into the normal condition becouse its still icey water effect i think :P
