Hi all, I've been spending some spare time getting re-acquainted with the engine and working on a shader that I had abandoned several years ago. I think I have it going well as the whole, and can now work on individual components in the shader.

Eventually, when I get the thing ironed out to my satisfaction I'll post the code in the Wiki with a tutorial. It is kind of a neat concept in my opinion. And something I had always wanted to incorporate into the game/level I could never see to make!

TODO:
-Continue to smooth out the pulsation effect
-Improve the specular component, add the fresnal effect
-Increase perturbation of environment map, fix artifacts, etc
-Change code for realtime reflection/refraction
-Produce a demo level and tutorial on the use

It looks really nice! I suggest adding a flowing shore map later, near by the terrain and on those perturbation lines (take a look at the screen):


Keep it up! Best regards!

Thanks for the suggestion!

Its good news to me seeing you back here at the forums, Steempipe. Keep it up!

Good to see you too, HeelX. I'm impressed with what you have done here!

Everything is great but where is the water.fx
no .fx no demo. :-(

Tele~ Thanks for the reminder. I've got to get back on it, and get the project/code cleaned up some.

@Steempipe
Thaks, I hope so ;-)

Making some minor progress on the flowmap shader. There is still alot of minor things to contend with, but it's slowly moving along. It's very difficult to deal with the pulsating effect and will probably be a situation where there will have to be compromise.

Current state:
-"reflections" with cubic environment map bumpmapping.
-Added a Fresnel term to control transparency.
-Added code for specular highlights from sun direction/color

Next goal is foam mapping.
