Terrain Water Level Question

Is there any way to have the water level rise or fall within an animation - simulating flood etc?

Just guessing, but my guess is you would have to elevate the terrain instead. If everything is ATTACH-ed to the terrain, that might not be too bad. I suppose the camera would need to have the terrain as a target, too.

I made a test of one way to do it.

1) Create a scene with just the water that you want. Place the camera to where the entire view is taken up by the water (looking at a fairly steep angle). Export a video of the water.

2) In the scene where you want rising water, place a plane from the "3D Space" props. In the diffuse channel of that plane, change it to the water video. Now you have a plane of water that you can raise/lower.

3) Play with the rotation of the plane so that the water flows in the right directly. Adjust the opacity and reflection. In my video I also increased the scale of the plane so the waves would appear to be getting larger.

It gets the point across, but you can probably make it look better with some particle effects of splashes, if the water is rising quickly.
