How do I get two way coupling in FLIP Fluids? I'm on Blender 2.91 and I'm trying to make a simulation with Suzanne being pushed around by liquid. No idea how I'd approach that though. Obviously I'm making it a rigid body and a fluid obstacle, but what should I do from there? There's no FLIP two way coupling option, is there?
Well flip and manta dont support this.
However maybe you can fake it.
If you use a paint canvas for displacment you can mimic it a bit.
If the water moves wild your out of luck though.
There are some raindrops examples that might work.
Else you need some proffesional solver and an openvdb import
(if it supports that) to render it in Blender.
btw there's a popular youtube channel 2 minute papers has lots of research about this topic, maybe through that you can find software that does it.
