Is it safe to assume that we can change the Spacing of a shot without changing it's timing, but cannot change the Timing without changing it's Spacing as a result?
You can think about like that, yes.
They are always linked.
So basically spacing is what distance the object travels in one frame. you can increase it to speed it up or decrease it to slow it down.
Hi Arsen,Yep. But it is also the path (direction) that it takes to get from point A to point B.
