That happens as the airbreak becomes a 1 poly wide object and rendering can not calculate curvature between vertices as there are only 2 which gives a straight line. Happens on many places and mesh connections.


You have to Edit normals on the airbreak mesh.

See this pic of the fuselage and wing connection. Same issue seemingly.


also in render



Select the fuselage and the 2 airbreaks then in the modifier roll down selet "Edit Normals"



Click on it and select it like you try to edit polys. It will give a hedgehog like view.



Scale it down to a size you will be comfortable. I use 0,3m.


Close in on the trouble area you should see some V spikes. Set "ignore backfacing" on.  Select always a single set of V-s Then press the button average, it will make that 2 like a single normal.


I made 5 of those to show.



And in the render the same section looks like this, Note the area front and behind where I changed nothing, the seam still shows up but between its "gone".



Hope it helps.




Edit: I forgot to add, when you finished with normal editing and satisfied with the result, right click on the Edit normal option and select, "collaps all"

Your welcome.

I would like to add one thing to it. Sometimes "average" is not the thing you want to apply, in those cases the given normal has to be selected, then its value copied over to the target normal which you want to look the same. That is used best when average gives strange result no not aimed for.

If results are not satisfying then you can always "reset" a normal to its original parameters, then try an other "way".

Your welcome, glad it worked out.


Cocas, might help if you make 2 polys on the place of the lower large one,  like half it, that way you have bit more playground with it. Just a thought.
