It is possible to create velocity only emitters. particular configuration creates a wind effect when combined with a large sphere or box overlapping with a fire emitter.

The key to velocity only is to set the Smoke/Temperature/Fuel Masks to 0.0. For wind, it is recommended to set Allocation Scale to 0.0, since the wind effect is only visible where the fire emitter is active. Note, the couple rate is set low in case to create a drag effect, which allows the general drift without stomping on the fire emitter.

same system can be applied to a fan, by having a smaller emitter region that varies the velocity in the blueprint based on the fan movement.

Thank you, I didnt know you could create a velocity only emitter. I’ll try in my current setup.
