I have an fliptank with container.

I have created velocity with source volume node but it seems like it only works when it is birthing new particles.

I just want to use that as velocity source (not to emit more extra flip particles)

How would I set-up a velocity volume that affect only existing flip particles ?

HELP!

In my understanding in order to have a better control of a custom velocity filed you need to create one in DOPs or you can use sop solver inside DOPS to change your current velocities with a vector field, the one on the source are going to affect mostly the birthing particles.

You could take a look on the Peter Quint videos or the Solver Masterclass on the tutorial session to have a better understanding how it works.


I hope that helps.

Check out the pump shelf tool - this allows you to set up a source that just affects velocity without emitting new particles.
