I need some help setting up rain im useing starter.fps i used a tutorial that i found in the resource on gg (forgot the name) to try and add rain , it didnt include an image for rain so i just copyed the images from the torque demo when i launch the game it just has a bunch of white boxes despite the help of the people in the irc chat room i stil cant get it to work
here is my weather.cs:


datablock AudioProfile(HeavyRainSound)
{
   filename    = "~/data/sound/environment/ambient/rain.ogg";
   description = AudioLooping2d;
};

datablock PrecipitationData(HeavyRain)
{ 
   type = 1; 
   materialList = "~/data/environment/rain.dml"; 
   soundProfile = "HeavyRainSound";                 
   sizeX = 0.1; 
   sizeY = 0.1; 

   movingBoxPer = 0.35; 
   divHeightVal = 1.5; 
   sizeBigBox = 1; 
   topBoxSpeed = 20; 
   frontBoxSpeed = 30; 
   topBoxDrawPer = 0.5; 
   bottomDrawHeight = 40; 
   skipIfPer = -0.3; 
   bottomSpeedPer = 1.0; 
   frontSpeedPer = 1.5; 
   frontRadiusPer = 0.5; 
};
and my mission rain datablock:
new Precipitation(HeavyRain) {
      position = "0 0 0";
      rotation = "1 0 0 0";
      scale = "1 1 1";
      dataBlock = "heavyRain";
      minSpeed = "0";
      maxSpeed = "0";
      minMass = "0.75";
      maxMass = "0.85";
      maxTurbulence = "0.1";
      turbulenceSpeed = "0.2";
      rotateWithCamVel = "1";
      useTurbulence = "0";
      numDrops = "500";
      boxWidth = "100";
      boxHeight = "100";
      doCollision = "1";
         color3 = "-1.000000 0.000000 0.000000 1.000000";
         offsetSpeed = "0.25";
         percentage = "0.5";
         minVelocity = "0.25";
         color1 = "0.600000 0.600000 0.600000 0.500000";
         locked = "true";
         maxVelocity = "1.5";
         maxNumDrops = "2000";
         color2 = "-1.000000 0.000000 0.000000 1.000000";
         MaxRadius = "125";
   };
and for my image i am useing rain.jpg and rain.alpha.jpg from the torque demo
please help me

If you have head version you must change
precipitationdata, the old data blocks is not working and the new code dont use dml.
thats why you get whiteboxes.

//try this in the mission
new Precipitation(Precipitation) {

dataBlock = "HeavyRain";

Im using this function for heavy rain

function startRain()
{
if (!isObject($Rain))
$Rain = new Precipitation() {
datablock = "HeavyRain";
percentage = "1";
color1 = "0.700000 0.700000 0.700000 1";
color2 = "-1.000000 0.000000 0.000000 1.000000";
color3 = "-1.000000 0.000000 0.000000 1.000000";
offsetSpeed = "0";
minVelocity = "0.25";
maxVelocity = "1.5";
maxNumDrops = "3000";
maxRadius = "10";
locked = "false";
};
}

I just merged with heads new rain code today, and pieced together these scripts. Everything works great.
datablock AudioProfile(HeavyRainSound)
{
   filename    = "~/data/sound/environmental/rain.ogg";
   description = AudioLooping2d;
};

datablock PrecipitationData(HeavyRain)
{
   soundProfile = "HeavyRainSound";

   dropTexture = "~/data/environment/rain";
   splashTexture = "~/data/environment/water_splash";
   dropSize = 0.75;
   splashSize = 0.2;
   useTrueBillboards = false;
   splashMS = 250;
};

function startHeavyRain()
{
   if (!isObject($Rain))
      $Rain = new Precipitation() {
         datablock = "HeavyRain";
         percentage = "1";
         color1 = "0.700000 0.700000 0.700000 1";
         color2 = "-1.000000 0.000000 0.000000 1.000000";
         color3 = "-1.000000 0.000000 0.000000 1.000000";
         offsetSpeed = "0";
         minVelocity = "4";
         maxVelocity = "5";
         maxNumDrops = "6000";
         maxRadius = "20";
         locked = "false";
      };
}

function stopRain()
{
   $Rain.delete();
}

Make sure you also grab the textures and sounds from /demo
