The most important feature of all fields is the distance control. In this tutorial, I will show you how to use animations of this parameter to make a wave on geometries.
Please note that the color ramp mode should not be set to the maximum value, but 0.1 less/more, so that the b-splane mode sets the gradient correctly. Also, when I created a wave, I use the same node to smooth out the appearance, but in the same way you can create other “obstacles”. On the gif, the wave does not hit other files, it decreases.
It is also worth paying attention to the settings of the mix position node. The offset of the positions must match the axis of the geometries.
