class FSimulationSpaceSettings

Remarks

Settings to control how much of world-space movement should get passed into the simulation. If all the Alpha values are set to 1, the simulation should be the same as a world-space simulation. Usually you would only change Alpha, but it is also possible to manipulate the elements of the phantom forces (like centrifugal force) if you know what you are doing.

Variables

Type	Name	Description
FReal	Alpha	Global multipler on the effects of simulation space movement.
FReal	AngularAccelerationAlpha	How much of the simulation frame's angular acceleration to pass onto the particles.
FReal	AngularVelocityAlpha	How much of the simulation frame's angular velocity to pass onto the particles (angular ether drag)
FReal	CentrifugalAlpha	How much of the centrifugal force to apply to the particles.
FReal	CoriolisAlpha	How much of the coriolis force to apply to the particles.
FReal	EulerAlpha	How much of the euler force to apply to the particles.
FVec3	ExternalLinearEtherDrag	An additional linear drag on top of the EtherDrag that can be set on the physics asset. Vector in simulation local space.
FReal	LinearAccelerationAlpha	How much of the simulation frame's linear acceleration to pass onto the particles.
FReal	LinearVelocityAlpha	How much of the simulation frame's linear velocity to pass onto the particles (linear ether drag)
