Description

To have a Particle System use an Emitter Delay Range that is chosen on each loop of the emitter, you must have under Duration, Duration Recalc Each Loop set to True.

Steps to Reproduce

1. Open QA Game Editor.
2. Create a New Particle System
3. In Cascade under the Required Module, set the Emitter Delay to 10
4. Set the Emitter Delay Low to 1
5. Set the Emitter Delay Use Range to True
6. In the Cascade Viewport, turn Particle Times on

RESULTS: The Emitter is Delayed always by the same amount which is chosen once between the set range.

7. In the Required Module, set Duration Recalc Each Loop to True

RESULTS: The Emitter is delayed each loop by a value selected between the range.

EXPECTED: Step 7 should be unnecessary or there should be a duplicate check box under Delay
