How to remove objects from simulation with clustered smoke

[harima]

Hi guys.

I have successfully managed to set up a clustered smoke simulation for a smoke trail.

Right now I am looking to optimise it a bit more.

So I would like to remove smokeobjects as the density goes almost to 0

Right now I am using a higher field cutoff value to the gas resizebounds node .

I think though that having the object completely removed once the density is low enough it would speed it even more.

 

Find file attached.

 

Thanks for the help!

Any ideas on that? Sorry to bump this, just giving it one more chance to get some help on this!

Thanks!

You can delete those Pyro objects where density is below threshold.

Yep but the problem is how?
I can see there is a DeleteDOP and I can straight reference a smokeobject and it will get deleted .
Problem is I am missing the way /syntax of telling it to do it in a dynamic way based on a condition (in this case density ).

May be something like this will help you:

Hi Dmitry, Thanks for your help, that's what I was looking for!  
Now I only need to understand these dop scary expressions :)
