are realtime fluid simulations possible in unity 6 preview?
I’m gonna say “Yes.”
But by all means, let us know, sounds like you’re perfectly set up to begin testing it.
Otherwise, if you’re contemplating doing a specific technical thing, your choices are to investigate support for that specific thing you need in the docs, or just give it a try and see.
I released Corgi Fluids - Burst/Jobified Fluid/Wave Simulation | Particles/Effects | Unity Asset Store recently, which is compatible with Unity 6.
