Simulating the waves

Now the part you have been waiting for – let’s create the dynamic paint simulation and simulate the raindrop effect! Let’s start by creating the canvas, and then we can move on to the brush objects:

1. Select the smaller plane object and head over to the Physics panel. Select Dynamic Paint, make sure that Type is set to Canvas, and click Add Canvas.
2. The Frame Start and End settings should already be the correct values we need. Let’s also make sure to change Sub-Steps to 5 to help make the simulation more accurate.

3. Head down to the Surface tab and set Surface Type to Waves. We are going to be changing some settings in Waves, so let’s go through them one by one:
   1. First, let’s turn on Open Borders so that the waves don’t bounce off the edge of the mesh.
   2. Next, change Timescale to 0.30 to slow down the simulation.
   3. Speed controls how...
