This is done with a level block or map entity!

What does it do with a terrain underneath, and fish models etc.?

Terrain is IMO the more reasonable combination with this water shader!

@Oliver and everyone else,
Replace the lines:

Code:

---

sampler BumpMap = sampler_state 
{
	texture=(entSkin3);
	MAGFILTER = LINEAR;
	MINFILTER = LINEAR;
	MIPFILTER = LINEAR;
};

sampler RefractionMap = sampler_state 
{
	texture=(entSkin2);
	MAGFILTER = LINEAR;
	MINFILTER = LINEAR;
	MIPFILTER = LINEAR;
};

sampler ReflectionMap = sampler_state 
{
	texture=(entSkin1);
	MAGFILTER = LINEAR;
	MINFILTER = LINEAR;
	MIPFILTER = LINEAR;
};

---

with:

Code:

---

sampler BumpMap = sampler_state 
{
   texture=(entSkin3);
   MinFilter = LINEAR;
   MagFilter = LINEAR;
   MipFilter = LINEAR;
   AddressU  = WRAP;
   AddressV  = WRAP;
};

sampler ReflectionMap = sampler_state 
{
   texture=(entSkin1);
   MagFilter = LINEAR;
   MipFilter = LINEAR;
   AddressU  = CLAMP;
   AddressV  = CLAMP;
   AddressW  = CLAMP;
};

That will get rid of the glitches that occur around the edge of the camera when it's over the water. Awesome job though.

With terrain... Sometimes I can see the terrain through the water's transparency, and sometimes I can't.

Here I can see the terrain:


Here I cannot:

You must make sure the terrain entity has an action that sets:
my.transparent=off;
my.flare=off;

and your water entity must be set:
my.transparent=on;

Thanks. It works!!!

Now... How can I change the ripple direction and velocity in this shader?

@Oliver,
Why are you using PS2.0 for the water effect? You could pull it off with 1.1, if all you need is enviromental bumpmapping. (or FFP envbumpmap, although that crashes on nvidia cards).

He is using HLSL... HLSL doesnt usually like shader versions below 2.0

Yes, I've tried 1.4 but there are some errors with instruction that I need. And I can only HLSL, no ASM. Why using environment mapping? Then there isn't a realtime reflection anymore.

Well, it's not "enviromental mapping", but is it not the same type of shader? - just instead you're applying a rendered view rather than a cube map. Like I said, if that being the case - You can do it in HLSL with ps1.1 and in just plain FFP (though like I said, ffp envbumpmap has compatability issues on nvidia cards). If I have some time, I'll try and fiddle with it.
