Variables

  Type Name Description
Protected variable FChaosSolversModule * ChaosModule Control module for Chaos - cached to avoid constantly hitting the module manager.

Protected variable UObject * Owner  
Protected variable TArray< TObjectPtr< UObject > > PieModifiedObjects List of objects that we modified during a PIE run for physics simulation caching.
Protected variable Chaos::FPhysicsSolver * SceneSolver Solver representing this scene.
Protected variable Chaos::ISpatialAccelerationCollection< Chaos::FAccelerationStructureHandle, Chaos::FReal, 3 > * SolverAccelerationStructure
