TUserDataManagerPT | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/ChaosUserDataPT

A chaos callback object which stores and allows access to user data associated with particles on the physics thread.

Note that FSimCallbackOutput is the output struct - this carries no data because this is a one-way callback. We use it basically just to marshal data in one direction.
