Unity 3D: Interact-able and Growing Fluid

Unity3d Engine Tycoon Tile (Terrain Package):[login to view URL] Ultimately looking for a fluid system that works exactly like the below video: [login to view URL] Features would be: Must support a 300 width, 300 length, 20 height terrain. Using Unitys scale Expand out of an object (More fluid is added to the scene and constantly grows) If the fluid is hit then it creates a wave like form. Similar to 1:25 minutes in the video. The fluid must have a gravity effect so it flows down hills If any part of the fluid separates from the main fluid then it should be removed, evaporates. A count of particles or percentage of fluid that the map holds. Like the guy has in the bottom left hand corner. Ability to change the terrain material that the fluid has crossed over Ability to set the texture/material of the fluid so it can be Water or Lava. The fluid must be able to stack up so it can fill the map up. At 2:50 minutes in the video you will see how the fluid has started taking over the land. At 10 minutes you can see how the fluid rises. 7 minutes also gives a good idea of this. The fluid must also be removed if it is hit by a projectile as the turret does to the fluid at 4:20. Settings should allow for the rate in which the fluid is spread to be set I had a look at NVIDIA Flex however it does not perform well at large scales. I had a look at [login to view URL] Its a good project but does not have what I want exactly and it is really buggy.
