Fan effect

[JuhaHo]

You can assign masses to particles and also have forces be affected by masses. Check out the relevant settings in the Mass and Force operators. From there it shouldn't be hard to tweak values so that 'heavy' particles aren't affected by your wind force as much as 'light' particles.

Thanks,

The problem is in placement of the airflow. I'm trying to have the air blow effect only in two gaps of 5 x 3 000 mm. However, when using the Force operators, those are affecting to very wide area - not in the narrow gap only.

So I miss a rectangular wind operator with dimensions of 5 x 3 000 mm. Like a rectangular spot light, where the light beam would be adjustable. instead of illuminating it should push the particles according to the imaginary light distribution.
