Realistic water node

I've improved the reflection shader and added flow maps for the water to get better results for things that are actually in the water. I have not added refraction yet but once I do it should be a pretty good alternative for water rendering.

I like the "flow" effect!

I finally managed to get a "Custom Three Layer Cloud Node" (tbw) reflected on a simple "Water Reflection Node" (elvman)..

The code is a mess, so I'll post it when it looks better..

Vectrotek I added Refraction to my water node I'll post some screenshots later.

Pictures are hard to see so I posted a video link.

For the love of god use clamp() on your refracted screen space coordinates, cause otherwise you'll refract from the other side of the screen at the edges... also grab the depth map and clamp against that so you dont refract from the stuff in front of the water

Materials are using ETC_CLAMP. I'll look in to it some more. Just got it up and running before I posted.

Found my mistake I set the array for the materials to be clamped after I set the materials.

Here's the new pictures:

If I use "createDeviceEX()" with HLSL/D3D and then rendering to a Render Target the Z Buffer has problems..
It also causes Occlusion Queries in Render Targets to malfunction.
(I hope its not my machine)

Here is Lensflare, 3 layers of Moving Clouds,
Water Reflection / Refraction (clamped properly),
FXAA Antialiassing and Posterization.

I think its possible to include the "Edge Wave Dampening" functionality offered by the extra "Depth Buffer" Render
WITHOUT that Depth Buffer Render using "Distance From Plane" where the plane would be parallel to
the water. If it works then EVERYTHING can be done in the water shader without the need
to render the depth and all those complex calculations seen in tbw's XML based PostProc.
My version is based on Elvman's Water Node but will have lots of extra functionality.

Reflecting Lens Flare has a few problems.
The math involved makes it so that it can't be
reflected like everything else and the "Sprites"
or "Images" of the "Flares" will not be "Plane Clipped"
(used in water rendering) so I had to add a
function to the Water Renderer called
"ExcludeItems(ISceneNode* Node);" which
then sets this lens flare node to invisible
from within the water renderer itself. It worked.

Somehow the Billboard used for the sun itself
survived the "setVisible(false);" from the water
renderer so it reflects just fine.
Everything happens in a very specific order.

Also, when I disabled the cube map I had
to re-code all the Post Processor and Water Renderer
calls to setRenderTarget() to include the basis Background Colour.

I have a working formula for determining on which side of a plane a point is.
My question is: "Is it possible to emulate " PrivateVideoDriver->setClipPlane(0, refractionClipPlane, true);"
in a shader (GLSL or HLSL)" using such a formula?
