Keyframe settings to make 3d model spin 360 degrees

[stanchat]

I am trying to make a 3d model spin 360 degrees around the y-axis. The problem is the animation has a pause at the end. I am looking for a smooth animation so what should my keyframe settings be.



I have tried
Keyframe 1 (frame 0): 0 degrees
Keyframe 2 (frame 29): 360 degrees

I have also tried
Keyframe 1 (frame 0): 0 degrees
Keyframe 2 (frame 15): 180 degrees
Keyframe 3 (frame 29): 360 degrees

I tried this in ( Poser, 3DS Max 7 and Hash Animator) and I get the same result. I know I am doing something wrong.

Well, 360° is the same as 0°.

So... something like:

Keyframe 1 (frame 0): 0 degrees
Keyframe 2 (frame 10): 120 degrees
Keyframe 3 (frame 20): 240 degrees

edit: thats 12° per frame. So, frame 29 is 348° then. When it restarts its at 360° (or 0°) again.

Nothing wrong with your keyframes per se...

Check the in-tangents of the last keyframe. Most 3D apps auto ease-in and ease-out (soline vs. linear keyframes) when creating new keyframes. Most 3D apps also have animation curve / graph editors so you can tweak the "acceleration" of the animation.

Keyframes specify the time and pos/rot/scale, but not acceleration - that's only in the tangents of the animation curves.

Either what voxel said, or your problem may be that your first frame (0) and last (29) are identical? In which case, just disregard the last frame.

This works great!!

Thanks guys for your quick response...
