For example, rigid bodies and fluid. I know it's kind of possible by setting the rigid bodies as fluid obstacles, but it's not "true" interaction in that the fluid does not affect the rigid bodies...

By "true" interaction I mean where two (or more) physics systems affect each other simultaneously. For example, with rigid body and cloth, the rigid body affects the cloth but the cloth doesn't affect the rigid body (at least the way I'm doing it), so the rigid body just eventually stretches the cloth to an extreme and falls through...

Are there any ways to achieve this? (for any interaction, not just rigid bodies and fluid)

Or, if not, does anyone know whether there are any plans to implement this sort of feature?



There is no way to do true cross-simulation between the different physics systems right now. And I do not know of any on-going project that will bring about that functionality as of this time.
