Workaround in UE5.3:
UNiagaraComponent::TickComponent if (AgeDiff < 0.0f) { SystemInstanceController->Reset(FNiagaraSystemInstance::EResetMode::ResetAll); // modifier add SystemInstanceController->ManualTick(UE_KINDA_SMALL_NUMBER, nullptr); // modifier add AgeDiff = DesiredAge - SystemInstanceController->GetAge(); }
Result:
The rendering of the preview will continue to be maintained.
Expected:
Reset the rendering of the preview to follow the timeline
