Ok it seems you cannot rotate buildings facing degrees like you rotate units and doodads by changing the degrees. I have to use triggers. I use no events, no conditions, just action - make unit(the building generated on the map) face 360 degrees for 100000 seconds, which on the animation looks to be facing downward (south), thast why 360. But when i start the game the bulding doesnt face the angle, just remains as if the trigger is not working.
