Thanks NextDesign,
I watched those before, learned something good tutorial.

Though my stuff is bit more difficult. I need somehow make those two graphs independent from each other, as example if i modify one, speed, at selected time interval, frame, leaning angle graph shouldn't change or be affected by it. In graph editor they are displayed separately, but still..


Second problem is related to first one, how to keep frame positions (leaning angle and speed) even when I expand curve at front, add curve pints ect. ?

More details, I have two curves, one bigger one is with animation details those speed and leaning angle modifications, and I need to add other at front, to make animation more detailed. If I join both curves animation from first one wont disappear, but i loose ability to modify those, its like history is deleted.



---- here is the video of how it looks. I have two curves at the beginning, i join them and history dissapears from longer curve.

Shortcut would be to switch those path on time, it would be so much easier, is it possible ?
