Spawning particles of a different type

[wbk]

Well, you can change shape of the particles, anytime you want.
What is preventing you?
Just add a shape operator in second event, and it will override previous.

PhysX Switch set on disable, will remove any PhysX calculation.

As for spawning "fresh particles", as I said, I never had any issuers with above approach I mentioned, but you can also do another method.
You can create new TyFlow, and add Birth Flow, and Flow update operators, and the new TyFlow will just read from the first particles whatever values you want.. and from there.. you can do whatever you want.. spawn them.. delete them.. send them...
I often use it for complicated destructions.

Ah ok - so I think what I am missing is that it is intended that 'I should be' using different flows for different 'types' of particles.  So in my example of particle cars leaving behind trails of smoke.  Is that the cars should be one flow, and the smoke another flow referencing the car flow with the birth flow operator.
