In my animation the axe starts like this
and should end like this
But for some reason it not only rotates on the blue axis but also on the green one. Even if I only rotate it on the blue axis. So you can see here that it rotates to the side in the middle of the animation. But it should only rotate forward.
For the people who use blender: If I make an animation like this in blender than only the rotation axis changes that I change, but here I can see that al rotation axis numbers change when I only rotate it in one direction.
Can someone pls help me solve this?
