I need to apply dynamic paint to an object (say OB1) that is constrained to another (OB2)! The problem is that although OB1 is moving by changing OB2 location, its "real" position is fixed and thus, the waves do not appear (i.e. if I initialize OB1 location on my canvas plane the waves I want to achieve are in its fixed position). What am I doing wrong?

In the first image you can see that OB1 is attached to OB2 with a location contraint, but its location is (0,0,0). Note that OB1 is a brush, and a hole appears in location 0,0,0.

enter image description here

In the second image I displace OB2 and thus OB1. But nothing happens and the hole remains at location 0,0,0. As you can see "Plane" is the Canvas.

enter image description here

In this second image

I hope my explanation is clear :)
