Yeah, Jonathan removes the clamp overlap at some point when it was giving him trouble, but it’s a one off and maybe it’s easy to miss if you don’t know what that’s all about. But don’t worry about the troubles you’re going through, the model may be beginner friendly but there are core concepts involved and it takes time to soak them in. Just keep practicing and learning, things start to click after a while, Blender is a huge beast.
