So I'm trying to use the boolean modifier to use shape A to cut into shape B. But shape A just turns light blue and fails to cut into shape B whenever I apply the modifier.
Whenever I do press apply, the error message "applied modifier was not first, result may not be as expected" pops up. I've tried to move the boolean modifier over the mirror modifier, but that doesn't help.
I've also tried to recalculate normals for both shapes with no success.
does anyone know how to solve this???
Also, here's a copy of my project.
