Curious about the reason for the significant difference in quality between UE and Unity fluid.

‘zibra’, a realtime fluid simulation plugin, exists in both Unreal and Unity, but in Unity,
it digests more particles without difficulty and gives me a detailed description, whereas in unreal niagara fluid,
the number of particles that can be digested is small, so it looks more like jelly than liquid.
Does anyone know what mechanism the difference is due to?
