Insert Animation Key without deforming curve
I would like to know if anyone knows if there is a way to insert keys to an animation curve without deforming it.
In my example the cube simply moves from its position at frame 0 to the new position at frame 30.
(mybox = box width:5 height:5 length:5
sliderTime = 0f
move $ [-50,0,0]
sliderTime = 30
set animate on
move $ [100,50,25]
set animate off
sliderTime = 15f)
If now I insert a key at frame 15 the curves of the X,Y, and Z Position will change according to the selected In/Out Tangent Type. What i'm looking for is a way to insert keys to curves without deforming their curvature.
