Hi guys

I am struggling with the pop kill node

I want to delete particles after lets say 50 frames
what function or formula do i type inside the vex expression window of the pop kill node?

It seems houdini 16 does not have what the old houdini kill node had to specify this

Thank you

Correct me if I'm wrong but isn't this just what the life option does in the popnet birth tab? Also can I add what does the % mean in that expression?

Hi, neutrosophic, I think the option of typing a formula gives more flexibility in the way you can determine conditions that control the life span of particles. the % sign means houdini will execute a specific task at every specified number of frames, so in other words if I type a formula such as: $F%10==0 it means a specific function will be performed every 10 frames
