As you can see in this picture I was trying to create a face, but when I apply a subsurfaces modifier you get these black spots. Does anybody know how to fix this. thanks in advance.
It might be because the vertices in the mesh are not made properly positioned that the blender is not able to properly calculate how to apply the modifier. So try these:
- Recalculate the normals properly using: "Shift+N"
- Go to edit mode and remove duplicate vertices by "Merge by distance option" (make sure you set the proper distance in the dropdown menu). Also, make sure that there aren't overlapping faces
