So, I was following this blender tutorial and the first time I did it, it went swimmingly. Now I have a problem: whenever I copy the top of the doughnut and solidify it for the icing... the thickness goes INISDE the doughnut. This means that whenever I snap the icing to the face of the doughnut when trying to make the icing look runny, it always goes inside even when snap works.
But whenever I set the value to be negative: it nearly fixes this problem.
I have no idea why. Could someone please point me in the right direction? This almost works, but it still leaves the issue of the "Crease" setting not quite working properly.
