Even more realistic looking water

I do love the way the water currently looks, but if we could get some volumetric fog into it, and get the reflections working better that would be awesome. Here is a video of some pretty great looking water done with XNA. I believe this guys used cubemaps for the reflection though, which would not reflect our components accurately. The point is that the reflection and animation effect look very very good.

In fact, someone code this stuff in for me overnight as well, thanks :op

Isn't underwater shattering "just" a shader applied to the underwater terrain?

If I remember correct OGRE waves were implemented using a shaders as well.

The specular highlights in the water of the first video are relatively easy to do with proper normal mapping. All you need is a 3D noise texture to define the waves, or you could even do it mathematically without the noise texture.

The water have a strange behaviour when you start to go far from it. Just go up and than look down to see this behaviour.

The only strange thing I've noticed is when the weather systems are enabled the specularity is flickering. I'll begin working on that.

What symptoms are you having?

EDIT: I should mention that the specularity for the water isn't finished yet. Not until it works closer to something like in the links in this thread.

The water plane starts to shake.

The newest source should fix this problem. I was using an improper normal for the normal mapping.

I'm still not completely happy with the water, which is why I escalated the issue in the issues section, but it should be working slightly better for now.

No, it didn't fixed. Try moving the camera up a lot, and then look down to the water. You will see the water to shake a lot.

Ah, I see it now, I was seeing something different. If you disable the tide phases the shaking goes away, not sure why it is shaking to begin with though.

Seems the water just doesn't look right at that distance anyway.
