Hi,
I just added a spherical windzone to a chopper in a project I'm working on in order to test whether I could simulate the rotor turbulence and to my surprise, it actually worked quite well at first try. Sort of.
Basically, the particle effects in the scene seem to do the opposite of what I'd expect them to do - they're being pulled towards the center of the sphere instead of being pushed away.
Adding a negative wind value to the sphere works fine, but this makes the trees behave the wrong way instead. I also tried changing the external forces modifier on the particles to a negative value, but this makes other forces behave incorrectly.
Am I missing something about how this effect works at all? My understanding was that the wind was strongest in the center of the sphere and got weaker as it got further away, but should this push the smoke away from the center?
