well this is more accurate than real flow I guess…also next limit, you probably wouldn´t won´t that kind of expensive stuff.

These are more accurate stuff, but for visualisation, I would forget about doing it with particles in lightwave,
you could download the free version of blender and learn how to do liquids there and then export to lightwave.
Here´s a blender fluid sim rendered in lightwave it seems.

You can also download the Houdini apprentice and try the fluid engine in there, pretty easy to make an object fluid, and
it can export object sequence to lightwave…the tricky part is that those things needs to fake motion blur.
dstorm plugin physx has a liquid plugin and those particles behaves more naturally like liquids than lightwaves own.
no english page thou,

There´s been a rumor that a fluid plugin will arrive for lightwave, maybe showing up at
siggraph with a flowline quality to it, but it´s vague rumors check newtek forums.
