I am trying to make the X-rotation of one object directly affect the Y-rotation of a second object.

I tried using the Tranformation Constraint, however I was only able to map the X-rotation of the first object to the X rotation of the second and the same for the Y-rotation.

Thanks in advance!

To do it through the Transformation constraint, set your constraint this way (image below). Essentially, in the constraint, choose your controller object as Target, click on Rotation for both Map From and Map To. Under Map To, as you want X to control the Y rotation, choose Y Source Axis > X, choose the degree amplitude, you can set to -10° and 10°, for both the controller and the object, and enable the Extrapolate option so that it extrapolates beyond 10°.

2 cubes

Right mouse click on y-rotation > add driver

enter image description here

choose these settings

and you get:

    $\begingroup$ There's a slightly snappier way .. right-click in the Rotation > X field of Cube 1, and 'Copy as New Driver'. Right-click in the Rotation > Y field of Cube 2, and 'Paste Driver'. But.. you may still have to go to the Driver Editor if the relationship isn't 1->1. $\endgroup$ Aug 28 at 12:08
