The quest and script works great for this. The objects are pointing the correct direction every second.
Unfortunately, on every SetAngle update, the object vanishes and fades back in. So you get a 'blinking' effect on the objects.
I tried to fix this by placing an xmarker, and linking the enable state of the objects to the xmarker, with the 'pop in' check box checked. But that had no effect on the object blinking.
Does anyone know of a way to stop the blinking, or perhaps know of another way to change the Z angle of the objects?
EDIT: Nevermind.
It looks like SplineTranslateTo will rotate the object without blinking it out.
