At first , we should create a plane, add the meshsmooth modifier to the plane stack , use noise on the meshsmooth, set the associated parameters, then modify the animation curve between two key frames according to the actual situation. The method needs to adjust the many parameters, it is more complex to realize and the animation effect is not natural. So combining RealWave element in RealFlow software to simulate the lake wavesurface. We will receive a very good effect.
