Rotating gravity

[hammerbchen]

Hi,

In FumeFX you have FumeFX/Gravity helper to specify direction of gravity you want. How can I do this with PhoenixFD nightly? For example, I want my gravity toward camera, what is the right procedural to do it?

disable the standard gravity and add the plain force helper, it affects the simulation in the same way as the gravity but can be directed in arbitrary position

thank you!
what is the right value for plainforce? if I want it act as gravity?

I am trying to recreate this scene with PhoenixFD, but the movement of smoke are not quite as I expect. There are several issues, here the smoke src size is depends on particle size. In FumeFX, particle src have fade in fade out size control; on the countary with PhoenixFD, I have to change particle size (fade in fade out) in Particle Flow, which is a little bit tedious.

Hey,

In the PHXSource at the very bottom you can choose to use custom particle size and you can animate it. You can also use Time Base = Particle Age if you want to animate the particle size by age, instead of absolute. I think this should help you get the effect you are looking for.

Cheers!
