Is it possible to insert a keyframe without affecting the slope of the existing curve?
I want to do this because I’m animating some walk cycles etc to be used in Unity. Unity animations go from the action’s first keyframe to the last, so a clean animation loop must begin and end with a keyframe for all curves.
But what if the animation requires a smooth motion to occur across the loop? I can’t key a curve to go from the third last frame to the third frame because the loop needs to begin and terminate with a keyframe. I can throw a keyframe midway through the curve, but this affects the slope of the f-curve.
So again, I ask, is it possible to insert a keyframe without affecting the slope of the existing curve?
