Hello to all,

I have a problem of black spots on my mesh.

I have tried Shift + N or recalculate inside or outside, but it does not work.

Here is my problem:

and my blend:
11.blend (823.5 KB)

Thanks for your help,

A+

Hi.

You have a triangular hole here. Disable the Subdivision Modifier to get a clearer view:

Either close it (with “F”) or remove extra vertices (unless they serve a purpose)

In other area there’re double vertices - two vertices in one place. You can remove them by selecting the mesh, and go to Mesh > Merge > By Distance (hotkey: M).

Also, those black edges poking out of the mesh are edges that don’t form a face - you might want to get rid of them as well.
Same for vertices that just float in space.
