I'm a Blender beginner and I'm trying to create a pumpkin creature for my game.

The problem is that I am using a UV Sphere to create the pumpkin and using a Boolean Modifier to make the eye and nose holes in my pumpkin, but the mesh is looking somewhat strange.

The border has this "pinches" and I don't know how to solve that

I'm using a Subdivision Modifier to try to solve this problem, but it still looks strange.

I tried to make a new topology for this area, using a Plane with Subdivision and Shrinkwrap modifiers. It looks better, but still strange:

    $\begingroup$ Hello, boolean can create a bad topology, you can fix that, but the best is probably to create the hole from scratch (your second solution), or use a low-resolution object as boolean object, but maybe share your second object? Not sure why you think it doesn't work though... $\endgroup$
