I want the Niagara system to simulate at a certain time, And I Check the "Determinism" option like Pic1. When I Drag the timeline at the particle editor, the simulation results are determined. But at the game editor, the simulation results are random every time, my BP'logic is Pic2 and the result is Pic3. I just want to get the same result in the third second. Where is the error in my code? thanks for your help.
