Ocean and particle collision?

[oldiesgoodies]

Hi

I am trying to make my foam particles collide with the ocean surface, and I am not succeeding at all. I did look at the provided collision in the foam scene, even so in that scene particles are escaping colliding flat grid collision object(not the deformed ocean).

Does anyone know of a way to make particles that interact properly with the deforming ocean surface?

thanks

Hi,

in the collision POP, point to the ocean geometry instead of the default grid and just set the "Hint" parameter to -> "Deforming Geometry (Only Triangles)"...

and be sure that your ocean has been triangulated.

Cheers,

Emanuele

Thanks for the insight, but the thing is that I have tried all those already as you have described I used the tristrip Sop and another triangulation Sop, cannot remember now.

Really bizarre. If I plug a popnet to ocean surface inside the ocean surface model, it works. But if I merge ocean surface into a new object and then create a pop network it just does not work.

edit: When I use mesh as a source to generate particles, it does not work but when I just create a location as source inside the popnet, I get proper collisions. Puzzled here
