I'm trying to create a crumbling ground effect. I want the pieces of the crumbling ground to rotate back as they fall instead of staying flat (as the currently do). The problem (I think) is that as each particle is affected by the force pop, the particle origin rotates 90 degrees. I'm just trying to get a gradual natural rotation over time. I've been messing with the rotation and up vector pops, but haven't really gotten anything, just the same popping 90 degrees, on the frame they are affected by the force. I appreciate any advice. See attached file.
