im trying to make towers with spiral steps. kind of a castle style. i didnt carve anything, but i am getting weird screens. what am i doing wrong in these pictures. i need an easier way to make a spiral staircase fit inside a cylinder. i used clipping to make windows (which didnt really work and looks like shit). also the arch in the door has a glitch too, im not sure why. last thing, what part of this should i func wall?
