I made animated wind but doesn't seem to be working with the particle system do I have to set which objects will be influenced by the wind force?
I made animated wind but  doesn't seem to be working.  (The fighters have 2 meshes- one is Hair Particle and Particle Emitter. Hair keeps the particles on the surface and defines the fighters bodies, while Emitter - makes particle flow along the characters move).
Just move the wind near to your particle system and set the strength to e.g. 100. Then you will see a result.
