I'm trying to create the waves made by a ship as is sails. I've had success doing this with vertex displacement, but as I'm going to use it in a large body of water and from a distance I can't subdivide the surface enough to keep everything running smoothly.

This why I'm trying to do this with dynamic paint and using the output image sequence in the displacement node of of a glossy texture which acts as the water surface.

While I get some result in the wake, I don't get the V shaped bow wave normally found in a wake. See my test scene below:

Example

The settings I used:

settings

The displacement map that resulted:

displacement

This is an example I found online of what it should look like:

Proper displacement

Can anyone help me get this right?

  • $\begingroup$ But it does work for vertex displacement. Could there be some way to output the result of that into displacement maps? Then I could run those in isolation first and then add the result to my complex scene. $\endgroup$ – cybrbeast Apr 3 '15 at 20:18
  • $\begingroup$ Yes you can Bake the displacement with texture baking from the high-poly dynamic paint mesh to a simple plain. You would have to do that for every frame though or use a script to bake it for you.. $\endgroup$ – Jaroslav Jerryno Novotny Apr 3 '15 at 20:56

the problem is the settings you are using ( the clear one is the smoothness which is killing all the ripples leaving only a sharp tail ) you have to adjust the settings according to the object speed and size to get the desired results :

using the following settings on the canvas (default plane with no subdivisions ) :

I get the following results :

bake the dynamic paint and set the result as a texture for the plane
