Looking straight up, not only at a 300° angle

[alexey7783]

Hi guys,

I am trying to render an image of looking straight up to the ceiling. But that doesn't work, somehow this is restricted to a 300° angle. Looking straight down works, this is done by using an angle of 90°.

Can someone help me here? Why is this direction "disabled"?

Please help me, I need this function badly for my project, otherwise it doesn't work out [:((] and I am not a good programmer to do this on my own. I am actually a pretty bad programmer [:(]

Thank you so much and all the best

Alex
