Problem with smoke trail source

[andrulis]

Hello everyone!

I try to tweak smoke trail from particle without any forces. I have strange issue with that(((I have a lot of discusting mushrooms. I really like this simulation and this trails https://vimeo.com/69413806
Can you get me some advices about that? 

In my video file I tried to represent my current source(pscale), vel source(yellow vectors), only density and simulation with divergence.

I think I do something wrong with velocity source but I have tried really a lot of ways already.

Your velocity generation is bad

Hi Vitaliy,

As "Now" said

You need to change your source particles, make them more like trail, don't kill them so fast. It's easy way. 

I mean, you need something in the middle of the trail. To push it slightly

Also you could take a look at divergence field. But it'll be harder to control.

Cheers
