Hi all,

I have a following problem: I try to use an integer attribute (values 0 and 1 and the node is plugged into the first slot of Pop Network) and I want to drive the Activation in the Pop Force with this attribute. The problem is it doesn't work at all. ( I set the Input1 tab to First Context Geometry).
I tried to bring this attribute using the “point” function in the pop wrangle and geometry wrangle. I have also tried to use it in the Vex fields of the Pop Force. No luck.
I am sure I missed something. Can someone explain me how to do it properly?

Hi.
Activation parameter which you've mentioned does not evaluate per particle!
It is just global controller for activation/deactivation of the node itself.
Instead you can zero out the force vector for each particle you want via VEXpressions parameter.
Of course there are some other ways but this one probably is easiest one!
