Ships parts have currently no rotation animation?

I am currently designing a new ship and i tried to build a rotating gatling weapon system for that ship. In the Gal Civ 3 editor you just selected the part, clicked on animation and then on the speed slider and it began to rotate. In the current 1.04 version in Gal CIv 4 nothing happens. You can move the slider, but there is no animation. All the ship parts in the editor seem to be affected. (I have started the editor over the current "test version")
