Helo, i am wondering how to offset smoke simulation, treat it as if keyframes.
ie. you simulated 250 frames of smoke, you want the animation to start on frame 125
(ex. fluid simulations have "offset" slider )
I am answering myself, it is a workaround
Set the start of the animation to the desired frame. In the timeline tab, there should be a part that says "Start" and "End." Change the "Start" frame after you have finished baking to animate from that point.
