Makes surfaces of this shader refractive with r_water. The refraction\r
replaces the transparency of the texture. distort is used in conjunction with\r
the normalmap to simulate a nonplanar water surface.\r
-- dp_water <reflectmin> <reflectmax> <refractdistort> <reflectdistort> <refractr> <refractg> <refractb> <reflectr> <reflectg> <reflectb>\r
+- dp_water <reflectmin> <reflectmax> <refractdistort> <reflectdistort> <refractr> <refractg> <refractb> <reflectr> <reflectg> <reflectb> <alpha>\r
This combines the effects of dp_reflect and dp_refract to simulate a water\r
surface. However, the refraction and the reflection are mixed using a Fresnel\r
equation that makes the amount of reflection slide from reflectmin when\r
looking parallel to the water to reflectmax when looking directly into the\r
water. The result of this reflection/refraction mix is then layered BELOW the\r
texture of the shader, so basically, it "fills up" the alpha values of the\r
- water.\r
+ water. The alpha value is a multiplicator for the alpha value on the texture\r
+ - set this to a small value like 0.1 to emphasize the reflection and make\r
+ the water transparent; but if r_water is 0, alpha isn't used, so the water can\r
+ be very visible then too.\r
+- tcmod page <width> <height> <delay>\r
+ The texture is shifted by 1/<width> every <delay> seconds, and by 1/<height>\r
+ every <delay>*<width> seconds. It is some sort of animmap replacement that keeps\r
+ all animation frames in a single texture.\r
+ To use it, make a texture with the frames aligned in a grid like this:\r
+ 1 2 3 4\r
+ 5 6 7 8\r
+ then align it in Radiant so only one of the animation frames can be seen on\r
+ the surface, and specify "tcmod page 4 2 0.1". DP will then display the frames\r
+ in order and the cycle will repeat every 0.8 seconds.\r
