How to remove blockiness from Niagra fluid explosion, make it smooth?

Hi, I’m fairly new to Unreal and trying to get smooth explosions. It’s made using fluid rather than flipbook, I don’t need smooth playback as it will be used for VFX rather than for a game.


I’ve tried upping the Resolution Max Axis but that just seems to make it brighter and the blockiness remains.

I’m rendering with path tracing and using the movie render queue. Anti Aliasing samples don’t seem to affect it, it feels like the resolution of the explosion itself is too low.

Any help would be amazing, thankyou!
