Hello Nate and Harald! I have a question about the json structure of curves. The curve data is written as: "curve": [ 0.444, 0, 0.889, -50.57 ] I understand that the first two values indicate the outTanget handle position of the first key, the second two values indicate the inTangent handle position of the next key. But what I don't understand is: first and thrid value of "curve": [ 0.444, 0, 0.889, -50.57 ] second 0 means the y handle position outTangent, -50.57 means the y handle position inTangent of next key, but what is first x = 0.444 and last x = 0.889 means? Is normalized time between first and next keys or what?
