Wie kann ich den Wassershader von Steaapipe, der auf AcknexUnlimited angeboten wird, transparent machen? Das Ufer sieht nämlich sehr eigenartig aus, wenn das Wasser direkt in Sand übergeht, ohne, dass man den Meeresboden erkennen kann.

Hier nochmal der Shader-Code:

Code:

function mtl_ffpwater2_1()
{

///////////////////////////////////////////////
//  Lets make it scroll in some direction
//

  mtl.skill1 += time;		
  mtl.matrix41 = floatd(mtl.skill1,4000); 
   	

}

function mtl_ffpwater2_init()
{
  
  mtl.matrix11 = float(1.6); 	
  mtl.matrix22 = float(0.8);	
 
  bmap_to_mipmap(mtl.skin1);
  bmap_to_mipmap(mtl.skin2);
   bmap_to_mipmap(mtl.skin3);

  bmap_to_normals(mtl.skin1,0.5);

  //bmap_to_cubemap(mtl.Skin2);
  
  mtl.event = mtl_ffpwater2_1;

  mtl.enable_view = on;

}


material mtl_ffpwater2
 {
   skin1=waterbump2;
   skin2=envspec2;
   skin3=base2;

   event = mtl_ffpwater2_init;
   
   effect = "

     texture mtlSkin1;
     texture mtlSkin2;
     texture mtlSkin3;
	
      technique makewater2
        {
          
          pass p0
          {
	
	  Texture[0] = <mtlSkin3>;
