Keyframes not animating object When I try to key frame a plane it indicates with the yellow bar on the timeline that I have set the key frame, but as soon as I go to set another key frame or play the animation the yellow bar remains but the object goes back to normal.
When I play the animation the object is idle as if there is no key frame. I have already searched a while on the web for this and found something on it but it had no solution.
Your question is a bit difficult to understand, but I believe I am answering.

It being a plane should not make a difference.

It sounds like you need to add another keyframe. If I am interpreting your question correctly, you are inserting a keyframe, moving/rotating/scaling the plane, relocating the time cursor, and watching all of your transformations revert to the keyframed loc/rot/scale. You can animate by inserting that original keyframe, NEXT moving the time cursor, changing the loc/rot/scale, and finally keyframing again. The plane should now change it's loc/rot/scale between the two keyframes.
