Modulate influences

The modulate_influence node varies the effect of an influence based on another property. For example, you can make particles more or less affected by wind_influence based on point_size.

1. Daisy-chain a modulate_influence node with the influences you want to modulate. The modulate_influence node can appear anywhere in the chain. The end of the chain must be plugged into the influence input of the graph's simulate node.

2. Specify the property that you want to use to modulate the effect of the influence. You must specify the exact property name, for example, point_size instead of size.

3. Set the other parameters as desired:

   • min is the smallest proportion of the influence effect to apply, and max is the largest proportion.
   • invert reverses the modulation, so that the influence is applied less where the specified property is larger.
