Pixxo 3D shows how you can trigger things in Blender with an Empty and the Vertex Weight Proximity Modifier.

A new tutorial from Pixxo 3D Juandre (Jay) Labuschagne shows just how useful the Vertex Weight Proximity Modifier is in Blender. The tutorial shows how you can create a setup using an Empty to drive events based on vertex weights on an object.

The proximity modifier sets the weight for any vertex based on the distance to a target, making it ideal for controlling many things. This modifier is super useful for more advanced Blender effects.
