Animation has smooth start and end?

Postby VaconCamp » Sat Sep 29, 2012 4:42 pm

So I'm modeling an Earth in blender and I made a quick 5 second animation of the Earth rotating, I'm going to use the animation as my desktop background and it's going to replay over and over. So basically I'm rotating the Earth 360 degrees so it can replay seamlessly without it looking like the Earth does one rotation and the animation starts again. The only problem is at the start of the animation the Earth starts slowly and accelerates and at the end it slows down. How can I get it to stay at the same constant speed without ever accelerating and decelerating?

Here is the link to the render: http://www.youtube.com/watch?v=2H_xFVu_V1w

I know the Earth is rotating the wrong way and the resolution is horrible but remember this was just a test to see if it would work.

Thanks in advance to anyone who can help me :)

Change the curve interpolation so you are not doing ease-in/ease-out.

in F-Curve Editor, select the desired keyframes, hit T and set interpolation to LINEAR
I'm sitting, waiting, wishing, building Blender in superstition...

Thanks :), I did exactly that and now it works perfectly. Here is the link to my final render: http://www.youtube.com/watch?v=uuQ-Vj43Gw4
