ParticlePositionRotation TParticlePropertyBuffer< FParticlePositionRotation, EChaosProperty::XR > Setting bNoEntryIsHead = false in TParticlePropertyBuffer allows us to not cache the data each frame and it will only return entries for a specific frame when fetched For example, we don't need to cache a kinematic target that is set to None, instead we only cache when it's not set to None and if we don't have an entry for a specific frame we can expect it to be a None kinematic target.
