I'm trying to fracture a bridge that is, I'm certain, all closed up and watertight, but I keep getting a few spiky polygon rays that spread out and pass through other arches of the bridge.

I'm wondering if I've missed something on my model, or if it's a limitation of Fracture.

It's no problem, happy to break the model up a bit and fracture individual sections, but it would be good to know if I need to do this, or if I need to get better at checking my model!
