Normals problem

Hello everyone,

i have an issue regarding a hull i’m currently creating. When i switch on Face Orientation I’ve got this :

Could you explain what’s the issue please ?

The normals seem to be in the right direction though

It looks like your model has no thickness; your screenshot shows what I would expect to see.

ETA: ah, you’re talking about that checkerboard pattern. I couldn’t see this as obviously on my other device.

Duplicate / overlapping geometry maybe…

can you turn of the mirror modifier please?

I’ve tried using solidify modifier but didn’t work either.

here a screenshot of the hull with the mirror modifier turned off

All objects are hidden. Still the same problem

I was thinking about overlapping geometry on that object.
Something you could fix with M / By Distance.
Can you post the .blend file ?

that is so weird. This happen when i delete a vertex.


Yes of course, here is is
HULL.blend (1.5 MB)

In Edit Mode / Face Selection > alt + H.
That will show you those overlapping polygons :wink:

Yes that’s right. I could have beem more specific

Thank you very much Picto.

What mistake could I have made ?

I don’t see how you could accidentally duplicate polygons in this particular pattern.
But there are plenty of opportunities to screw up when modeling in Blender :sweat_smile:

I totally agree with you. Well thank you anyway

Best regards
