actually I have a permeability problem with a surface ocean which collide with particles.
When I animate the ocean’s time parameter, an important part of the particles cross the ocean surface in spite of a collision permeability parameter at zero.
Is anybody knows the solution ?

Maybe modifiers order is not good. Collision modifier should be after Ocean modifier.
Maybe particle system cache step is too high. By default, its value = 10. Try to set it to 1.
If it is still not enough; try another integrator like RK4 or subframes.
The solution is the subframe. Thank’s guy
