i need some ones help, can someone show tell me how to use a particle emitter
and make it look like water pouring out of a cup like at [url]http://www.youtube.com/watch?v=UebiF8cTUWg&feature=related.

The movie you posted was made with Realflow, and rendered with Lightwave.
Doing this completely in Lightwave is possible, but quite hard to achieve.
(an emitter with lots of bouncing sticky particles could do a decent job)
RealFlow is a program specificly designed to create fluids. And quite expensive as well.

For a cheaper alternative, I would suggest you try Blender, it has an decent fluid simulator and it's free.

i need u to tell me in detail how to make the fluid because I've been trying all week to do it but the particles always stick together.

Cant do anything like that example with LW particles. Convincing liquid requires large amounts of self-colliding particles. LW calculation bogs down well before you have enough self-colliding particles to do anything practical. RF demo version is full featured to learn and use, with tutorials on the site to get you started. Have also seen some promising things done with Blender which is free.

I will try Blender.

Check out this thread (http://www.newtek.com/forums/showthread.php?t=82397&highlight=water+blender) and this explanation (http://www.spinquad.com/forums/showthread.php?t=10042&highlight=blender+fluids) ..

Works well rendering in LW, but the trick is still to get motionblur working ... Realflow gives information which can be used to simulate the blur.

No it isn't...............it really isn't possible

I use realflow for that kind of stuff!

Sadly its true you can't get truly realistic water with out of the box LW. Blender is a great solution and free. ReaFlow is better but very pricey unless you work a lot with fluids and or have a major project which will cover its price.
It is possible to get semi realistic water with out of the box LW but not the particle separation like you are after. There are a couple workarounds to kinda, sorta cheat the process and get LW to get closer to being able to get through the Calculation process but its an extremely touchy process that is fraught with major headaches hence I won;t go into that mess today other then to say think about breaking the simulation up into extremely small frame increments to then comp them together later.

Cheating motion blur,

Cheers erikals! been waiting for such a workaround ...

it is kinda sad that lightwave hasn't gotten a fluid dynamic straight out the box yet. it would be a nice feature to have.
