External Forces module

This property modifies the effect of wind zones on particles emitted by the system.

Properties

Property Function
Multiplier Scale value applied to wind zone forces.

Details

A Terrain can incorporate wind zones which affect the movement of trees on the landscape. Enabling this section allows the wind zones to blow particles from the system. The Multiplier value lets you scale the effect of the wind on the particles, since they will often be blown more strongly than tree branches.
