Rigd body and soft body combined?

[jm]

I'm trying to get a surfboard and a leash to dynamically interact with a realwave in an ocean simulation. I want the surfboard to be a rigid body; and I want the leash to move and bend with the ocean current. What is the best way to do this?

Thanks!

make the surfboard an active rigid body, the leash a soft body and connect them with a multijoint constraint(under the objects category). I advise you to use the GridDomain to make the ocean so you'll have particles interacting with both, the leash and the surfboard. Not sure about the realwave...

EDIT: Ouch, i forgot it's a Realflow 3 topic. As far as i remember you got a fixed constraint , but you can only use it to bind 2 rigid objects. Softbodies can be linked to rigid bodies only by scripting in RF3. Taking a group of vertices and updating their positions on every frame, so the rest of the vertices follow along
