Is there a way to enable interactions with a unity particle system and Obi Soft body?...i suspect not

I seem to suspect it shoudl be possible with an OBI partilce system....but i cant seem to find out how to create an Obi Particle emitter... ( i have Obi soft body and Cloth)

essentially i want to simulate a  ( bio science) cell being targetted by a swarm of rigid body spheres.


any advice much appreciated

thanks,
DUncan

No, it's not possible. Unity's particle system and Obi are two completely different, unrelated systems that know nothing about each other.

ObiEmitter is part of ObiFluid. Still, it just emits Obi particles which cannot interact with regular Unity particles.

Not sure how the rigidbody spheres and the Unity particle system are related in your use case, but if the cell is a ObiSoftbody and the rigidbody spheres are actual Rigidbodies this is doable.

 thanks Jose, i dont need obi partciles to interact with regular particles,
and i dont i need rigid bodies neccesarily, I just need a particle sytem that can spawn spheres that will  interact with a soft body.
Obi Fluid looks perfect. Many thanks, will add it to the collection.

Iim  assuming i can simulate all kind of physics with the obi partciles...not jsut fluid dynamics...( ie much simpler particle forces) thanks again. i will get obi fluid.
