Smoke Man Effect

[r4ZR 0]

Hey everyone,

 

I'm still kinda new to Houdini and right now I'm trying to get a similar effect like it is shown in this video https://vimeo.com/110820797.

I used one of the animated characters in Houdini and put the 'Billowy Smoke' "onto" it.

The effect works, but I still have some issues which I can't solve by myself.

At around frame 45 the smoke man is not displayed completely anymore. The legs kind of disappear.

To check this issues, I also took a sphere as the smoke emitter and I noticed that the sphere already was not fully displayed in frame 1.

You'll see the issues on my screenshots.

I have really no clue what's causing this and therefore I hope some of you can help me solving this.

 

Thanks in advance,

Hey so i had a look at your file and looks like  that you have animated noise turned on in fluid source, try changing that or turn it off , you'll be good to go.

Thanks, that fixed my problem!

It was literally one of the things I did not suspect to cause the problem .

 

But I'm still wondering a little.. I recreated the scene and on this scene the noise was also turned on, but I didn't get the issue I had before.

According to the scene scale you have to change the turbulence values, as it affects the density. Lower the scene scale lower the turbulence values.

Now everything works fine, thanks again!

Hi, this is probably a stupid question, but I have been playing around with the same type of effect, but I am slightly confused as to what exactly binds the smoke to the body. i find that the smoke just fill up the container too much, so the shape disappear. How or where can I control this more?
