When you say the clay breaks, are you using a “Destroy Actor” node on it? I wonder if it’s possible that you’re destroying the clay before the colliding projectile has a chance to read all the values from it. One tactic I’ve used is to disable collision and set the actor to not be visible and this will effectively “destroy” the actor (as far as the player sees) but you can still access the values from it… then Destroy it when you’re done. That might not be the issue though
