Rereading now and do you want to use the slider as a = multiplier? So when the slider is at 1 the object is on the path... At 0 = the object would be at  0,0,0  at 2 the object would be double = the position of the current time?

Is this what you = mean?

Sort of like scaling the entire motion path of keys in = one or all directions, but tying that to a slider, so that when the = slider is at 0, there is no motion. ie it clamps all values to = 0.

There is probably an easier way to do this but I was wondering if = this it was possible like this. = Thanks,
