After widening the hat brim, I leave a comment to help those who do not bend down. When I made the gat shape at 5:38, the teacher's scale x, y, and z axes was 1.521, and the gat I made was - the price. That's why it didn't bend down... Even at 6:14 seconds, when you make brim inside, it can be bigger or smaller than that, but when you make a gat or inner brim, if it falls into a negative price, it always twists when you bend from the outside to the inside. I think you need to check the figures that you use. I hope it was helpful. I'm going to move on to the next lecture!
