Why is my subdivision not working properly in a specific location?

[Fendi (Danylo Bilonoh)]

I have a problem that the modifier is not working properly.

This is roughly how it should look.

The bit where the edge isn’t crisp?

Have you checked that it has the same level of crease (purple lines) as the rest of the edges?

[Fendi (Danylo Bilonoh)]

Yes, all 1

Could you deactivate the subD mod and make another screen, it’s clipping into the overlay.

This pole (the yellow edge loop) is causing that.

You would have to move that edge somewhere (away from that beveled edge).

Here is a similar problem

and a possible solution
