I am playing with rigid bodies in 2.79 and I'm having the following problem.
I have subdivided a plane a few times, then added subsurface and displace modifiers. I animated the displacement with a cloud texture and an animated null. A rigid body physic was also added to the plane (with 'passive', 'animated', 'mesh', and 'deforming' selected).
This creates an animated pseudo ocean surface.
I then add a few icospheres in the scene, on top of the plane. They are simply active rigid bodies.
When I do the Free Bake of the Rigid Bodies, the Icospheres instead of interacting with the animated and displaced plane, they simply rest on the original flat plane.
Am I doing something wrong or displaced animated objects cannot be rigid bodies in Blender?
Many thanks for any comment and advice.
