it's just a star shaped bloom shader >.>
( you're clearly playing too much shooters xP )
edit: it's just the suns brightness I guess.. it should be waay higher but I didn't want you to go blind
with a little bit more realistic brightness, staring directly into the sun would look like this

but thanks! (even if the water shader could use a lot of work and optimizations ._.)

No, thats beautiful Kartoffel!!

First Version of a cut through shader.
Now i only need shading and normalmapping for use...

Now that looks nice... specific use or just for fun?

More proove of concept, but with a specifc use in background. but isn't useable right now cause it just causes one slice...

Still really cool

@MasterQ32:
Valve released a Paper about this topic, as they needed this in L4D 2. Though i can't remember where it was :|

I have it on my computer. I'm wondering if it will work with Gamestudio as it needs the stencil buffer...
And i have no experience using it....

reworked my water shader, and modified the editor panel accordingly. hopefully it can produce less plastic-like results, and if using a higher poly water terrain (65x65) vertex waves have real effect (but it could be improved further). shore fade-out is also smooth now.

new reorganized gui:


stronger ripples (normal map based) and vertex waves:


blending in a foam texture (can be set to have wave height dependent intensity):


and one without foam:
