I'm currently learning blender as a beginner by Blender Guru. When I was making the mug, I had to extrude the top to form the interior of the mug. But as I was extruding the top part of the mug, the top part of the mug is seen and the interior is not shown. Here are the screenshots:
I was thinking the problem was the inset above the cup. But I tried to fix it many amount of times but it gives the same problem. The interior of the cup should be seen. Is there a way to solve this problem?
