FCollisionParticlePairKey | Unreal Engine 5.7 Documentation

API > API/Runtime > API/Runtime/Chaos

A key which uniquely identifes a particle pair for use by the collision detection system. This key can optionally be the same if particles order is reversed (see bSymmetric constructor parameter).

This uses ParticleID and truncates it to 31 bits (from 32)
