Make Niagara Sim Cache Capture Parameters | Unreal Engine 5.7 Documentation

Adds a node that create a 'Niagara Sim Cache Capture Parameters' from its members

Inputs

Type	Name	Description
boolean	Append To Sim Cache	When enabled we will append to the existing simulation cache rather than destroying the existing contents.
boolean	Capture Fixed Number Of Frames	When enabled we capture NumFrames number of frames, otherwise the capture will continue until cancelled or the simulation is complete.
integer	Num Frames	The max number of frames to capture. The capture will stop when the simulation completes or we have rendered this many frames, whichever happens first.Set to 0 to capture until simulation completes.
integer	Capture Rate	Allows for reducing the frequency of captured frames in relation to the simulation's frames. The ratio is 1 / CaptureRate, so a CaptureRate of 2 would captures frames 0, 2, 4, etc.
boolean	Use Timeout	When enabled the capture will time out if we reach the defined number of frames without anything new to capture.
integer	Timeout Frame Count	When we fail to capture a new frame after this many frames the capture will complete automatically.
boolean	Capture All Frames Immediatly	When enabled we will capture all the requested frames immediatly.This will capture the simulation outside of the main work tick, i.e. if you request a 10 frame capture we will loop capturing 10 frames on the capture call rather than over 10 world ticks.
real	Immediate Capture Delta Time	The delta time in seconds to use when manually advancing the simulation.Defaults to 1 / 60th of a second(0.01666).
