Thanks sir I will try this

Hello!

I am currently working on a fire moving in space and its embers. I am using a simple popnet for these particles folowed by trails, with the fire as an emitter.

But the fact is, the fire is only "emitting" these embers, and there is no any velocity interaction between the fire, meaning when it's moving violently, the particles are still just emitted and moving to the sky, disregarding totally how the fire is moving, to move with it while created before going to the sky, I don't know how to have this inerty.

I tried all the pop nodes and some wrangle stuff but nothing seems to really work

If you have any ideas on how to create this particular interaction it will be great !

Okay I have found the solution for those who are blocked :

In the hairgen you have to write the velocity attribute in the guide point attributes (V)
You have to be sure to enable the velocity blur, always in the hairgen.

In the RIS, you have to rise up the subframes up to to minimum.

And normally, you will have your blur and your dpd aov Ok.

Hope this will help !
