well you can setup a pretty basic system relatively fast using 3-5 events.

1. Birth with shape of mound of the water.
2. Flow down the river, you can use speed by surface for a more complex surface
(i created a defelector at the top of the river, so my water tensioned particles don't go above the surface)
3. Particles will become affected by gravity and drag at the end (a deflector triggers the fall)
4. Particles are spawned on impact of the water below.
5. Particles die after second bounce.

For rendering try to use a lot of small boxes/ with lots of blur.

here is a quick test.

fume fx can actually create pretty good results.

Check that out. That's the test I created awhile ago using fumefx. I'd share the file, but it got corrupted :(

Basically just create particles like the other chap did and use fumefx on the particles. Use high gravity and low buoyancy in fumefx parameters.

Setup a particle flow system representative of the water motion, add a fumefx particle source, adjust the particle source size and the fume smoke dissipation till it looks right. I started building one little while back in my spare time but got busy. Still needs work but proof of concept

Test Here

Hi,

For me, it looks more smoke than the waterfall.
Thanks for the ideas. But this is not working for me.

I have my waterfall done previously using pflow, I get pretty decent look by compsiting them, adding mist, fog etc.
I need to get the feeling of chunkiness in the volume of water, like in the link i had given earlier,
I am missing that, and i have quite a small amout of time to do rnd by myself.
so I need help to get it done quickly as possible.

thanks

sachin

Perhaps if you post what you developed so far that you are happy with, it would help to get you pointed in the right direction.

Here's another example using stock 3dmax tools but I'm guessing you already looked into this:
http://www.highend3d.com/3dsmax/tut...torial-350.html

There was a sample file years ago that included a scene which used this method and looked really quite nice.

You know I was wondering if it would be possible to get a look @ that scene file?

back...

attached is the 3dsmax scene it was created in max 2009.

also here is a link to a movie with a pwrapper over the particles.

this is a lower amount of particles and a high wrapper drop size, so the detail isnt tremendous... but the more particles you use and smaller drop size it shouldnt look so blobby. add a lot of motion blur and a kickbutt animated displacement for the wakes and you'd be half way there.

best,
nick
