Can someone else throw down a rotation pop for some particles and for Axis Type Vector put vector3(rand($ID), rand($ID+1), rand($ID+2))
My hip crashing whenever I put this expression in there. This should work right? I'm positive I've done this before. I'm using H9.

it's not crashing for me
but it also doesn't appear to do anything…

The “RotateBasic” example included in the help card for the Rotate Pop does exactly what you have done. It works and doesn't crash for me.
