How to make non-linear movements with a Follow Path constraint? I try to achieve a non linear movement with the Follow Path constraint.
I linked my object to a bezier circle using the Follow Path constraint.
It follows the circle with a linear movement, meaning the speed of the object always stays the same.
I want to make the object move faster by time, by changing the curve of the evaluation time from linear to exponentially.
In short I want the movement of the object to get faster and faster. How can i achieve this?
The Evaluation Time property is keyframable, you can shape its F-curve to any function you like.
Select your bezier curve object, in the graph editor and expand it to show the Evaluation Time curve (add a keyframe if necessary if it doesn't show by default).
Under the Modifier panel add a Generator modifier, change poly order to $2$, and adjust the function to get the desired speed.
