Hello

I want to rotate each primitive in my geo so the “center” points line up in 90 degree intervales by using acos from the calculated normal on the current prim with a standard (0,1,0) normal. but obviously im doing it wrong.

Anyone have any input in what i am doing wrong ?

Solved it and added some more features to it aswell, like clipping the ends.
