Syntax

uint8 bUseLegacyEmitterTime: 1

Remarks

If true, the EmitterTime for the emitter will be calculated by modulating the SecondsSinceCreation by the EmitterDuration. As this can lead to issues w/ looping and variable duration, a new approach has been implemented. If false, this new approach is utilized, and the EmitterTime is simply incremented by DeltaTime each tick. When the emitter loops, it adjusts the EmitterTime by the current EmitterDuration resulting in proper looping/delay behavior.
