    I understand that to create a seamless loop the last frame must be the same as the first. I’ve run into a problem that I’m trying to solve whereas the rotation of frame 1 of an object is 370 and the last frame is 740. How can get the layer to loop when the two keyframes are different ?

    I’m not sure I understand your question … I think you meant those as rotation degree values (not frames) … if so, just make them a few degrees apart. I say “a few” because how many depends on the degree of rotation between any other two frames in the animation. Related to that, they shouldnt be the same because that’ll create a one frame stutter at the loop point instead of a fluid loop.

    I don’t understand 🙂 Don’t I have them a few degrees apart since one keyframe is at 370 and the other is at 740?

    Actually, upon second look at your question I realize the numbers you gave can’t represent rotation values since, if they did, they would only go as high as 360 then start over. In order to answer your question, I’d need clarification of what the numbers you gave represent (i.e. position keyframes, etc.) … and even a little more info about what you’re trying to do would probably help.

    By the way, the things I said still hold true … just don’t seem to apply to what you’re doing since it seems like you’re not actually talking about rotation. And, when I said “they shouldn’t be the same because that’ll create a one frame stutter at the loop point instead of a fluid loop” I was trying to point out that it wasn’t entirely accurate when you said “to create a seamless loop the last frame must be the same as the first”.

    What I have setup is a rotation loop, confusing enough 🙂 If I copy the first frame the same as the last it won’t rotate. The rotation I currently have setup is the way I want it, but when it restarts to the beginning it’s not seamless, I’m using invigorator for the rotation of the object.

    What I was pointing out what not accurate ?

    The confusion is in that you failed to mention that you’re referring to rotation inside of a third-party plugin that may not use the same standards as AE’s native rotations (AE rotations only go from 0 to 360). I use Invigorator and know it can generate a rotation loop, but I’d have to create one in order to explain in detail what the values should be and, I’m sorry, but I don’t have time to do that. If you don’t get a sufficient answer here, you might try the Zaxwerks forum.

    Although there are instances when it won’t matter, generally speaking, if the first and last frames of a loop are exactly the same, the animation will repeat two identical frames at the loop point so the animation will appear to stutter for one frame instead of loop fluidly … sorry, I doubt I can explain any better than that.

    I understand my fault for failing to mention I was using a plug-in. I do understand to a degree what you mean about the loop, I will just go and ask in the Zaxwerks forum.

    Thank You, Dave for your time !
