Dark Grey Area after Subdivision in Edit Mode

Hey there,

im pretty new in Blender and i started a Tut-Series on YouTube. Right now modeling an anvil.
My problem is that after i use the subdivision modifier, i get weird dark grey spots on my model when im in edit mode.

Hope someone can help me :slight_smile:


When you subdivide parts smooth, faces may not line up exactly on the same place as the actual geometry. At the base of the anvil, the smoothing makes the subdivision rounded and not aligned perfectly. This is fine though, nothing to worry about.
