Does anyone know to use VEX nodes to create simple particle controls in POPs?
The best I have managed to come up is to create a Location POP and using a simple VEX particle node and in that node I simply add some random nodes but its makes no sense to me…. so if anyone can suggest me some good combinations of nodes to launch me off please do
Any examples of hip files would be much grateful too
thanks in advance….

For an example, append a VEX Sprinkler POP to a default Location POP. Hit play to see the effect. Now in the VEX Sprinkler POP's Parameters Pane, click on the “Edit VEX Function” button. In the new Operator Type Properties… dialog that opens, go to the VEX Code tab. Now you have some example VEX code. As an exercise, you could try converting that to a VOP network.

Note also that if an attribute name in an upstream POP matches that of a parameter in the Vex POP, the contents of that attribute will control the parameter. It's a great way to get unique per-particle control.
