Day and night cycle with customized initial sun position

Hey guys! So i made a day and night cycle which works fine. My problem is that i’ve created a whole level before doing that. So when i did that day/night cycle i noticed the sun was rotating in a wrong way. (From south to north, when i want it to come from east to west) . I managed to correct that by rotating the sun myself so that it fits my will. The problem now is that my sun doesnt go “deep” enough (can see that on sun height which goes from -0.5 to 0.5 instead of -1 to 1). If you guys dont understand what i mean, i can post pictures.
Basically, what i want is to make it go to -1 again, even with my intial rotation.
Thanks,
Ryan
