I wanted to animate eyes blink, and I used shape key for that. I create Basis shape key, and than Blink shape key. I move points in Blink to the appropriate position. And everything is fine if I only want to use 0 or 1 value on that shape key. But there is a issue that i don’t know how to solve. During the 0 to 1 value interpolation points move strictly linear from start point to end point (side A on the picture). But I want that they move by the curve (side B on the picture).
How can I achieve that?
