As I started thread, isaid I need quick way to do this. And explaining what to do is difficult for me I guess. I will explain through example, hope it will be more clear. Lets say I have care moving according curve. I need to work on two things of that car, speed and leaning angles on corners. Lets say I have done speed and leaning anles for whole path. But I noticed that at some point car goes too fast, so i open graph editor, and lower the speed of car. But then problem appears, not only speed changes, but as well car now leans at wrong place in path. Thats exactly what I'm having with my project. I change speed at part where it should go slower, but at the same time other graph of leaning (out ow two, "leaning and speed") changes as well. Your question still isn't clear. What are you trying to make independent? Just saying "these two curves" is not helpful. What is it doing now, and what do you want it to do?
