As you know, Earth rotates around it's axis in an angle of 23.5 degrees. How do I make a sphere in Blender rotate like this?
There are a few options
- Use axis-angle rotation mode
(a direct answer to your question).
- Set the euler-rotation order so Z is applied last.
- Use an empty parent, for the tilt and simply animate the child meshes Z axis.
(I'd do this, it generally gives more control so the spin and the tilt independently).
- You could use Copy Rotation constraint, but I don't think theres much advantage to this.
