Hey guys! I just wanted to ask if anyone has some ideas to make this.

EDIT: I was thinking about texture with animated perlin noise as the water has but instead of using it as a heightmap using it as a alpha map for the darker color…

I would suggest creating a sphere and just adding a texture like that in the picture to it. however If you want the texture to be animated I think you need unity pro but im not sure, hence only writing a comment

I have pro and yes I wan't it animated :)

ok I don't have pro so I'm afraid I can't test anything I say but I think you would need a custom shader as the movie files get converted to theora in unity which doesn't support alpha, therefore you need one movie with the RGB and one thats just for Alpha then you use that with a custom shader. as i said i can't test anything but this one:http://answers.unity3d.com/questions/9750/movie-texture-blending.html on that page sounds like what I would guess would be needed, making the movie texture is down to you though sorry.

Making a movie texture is one thing but I would rather like to make it by code...

Read up on this: "Special Effects with Depth" talk at SIGGRAPH | Unity Blog It looks like one of the effects they discuss is pretty similar.

Also you can animate textures either by using SetPixels(32) or the GL extension (See OpenNI) for better performance. And/or you can always change textures (page-flip animation, or tile/UV animation, although for this I wouldn’t use tile/UV).

You could write/buy a dissolve shader, and just change the direction that it moves (dissolve in/dissolve out)
There are a couple on the Asset Store, the cheapest is only $5
