Hey, I'm new to Houdini and I was wondering if anyone knew the best way to create dust particles falling.

I've got my animated creature jumping onto a wall and I need a slight drop of dust.

Thanks guys.

Make surface or the area of the surface an emmiter for POPs. Key the frame of the emmision for a few frames.

or start watching this https://vimeo.com/81611332 [vimeo.com]

Also you can use Billowy Smoke (with downward Buoyancy )for dust and Advect your particles inside of dust with POP Advect by Volume node for soils 8)

This is a very very simple example , you should use more and better setting , lighting and shader to take better result 8)

Thanks Joker, its definitely a great start. I'm just going through it all and trying to get my head around it all. It's surprising but it allows me to really understand the process. This is great teaching material for me!

I working on a VFX shot that contain a Big destruction with dust and soil for now.

At the first I made a Dynamic setup for fracturing,
Then I used two different particle system , one of them used for soils that generating from each piece .
And another one used Advected by Volume feature for making blowing effect.
Also I used another Pyro dynamic for making extra Dust effect.

I think final result is great with perfect detail.

Just one important thing is I generate 10,000,000 particles for soils , Then I use Point Replicate SOP for increasing number of particles to 100,000,000 , So final result in the rendering have perfect detail.

Another important thing in the rendering is you can use Geometry Filter Width option for decreasing render time , Because in this case you can use smaller number for Pixel Samples.

NOTE : Don't forget to use Motion Blur for particles.

I'll upload it after finishing :wink:

Hi,

Rendering some mantra points at the moment, but I am struggling to find this parameter you mention

Geometry Filter Width

Where exactly is it? Using H14!

Thanks,
