Use Face Orientation To Locate Incorrect Normals And How To Fix Them - Blender 2.8 Tutorial

For this tutorial, we will demonstrate the easiest ways you can locate incorrect normals, which have a negative effect on models exported to game engines, and cover how we can fix any incorrect normals with just a couple of button presses.

40 min of shift+n, ctrl+n, shift+ctrl+n, other options, manually recalculating.
this is just the greatest answer.
THANK YOU, this will save so much time over trying to do it manually

You're a legend, I've been working non stop hours, and days just trying to fix this problem. The solution was so simple :')

[lottos_tanktop]

i always forget how to do this, so thank you. i hope anyone having trouble with wrong facing faces finds this helpful

[Payne.Heartnet]

Omg thhank you so so much!!! You saved my 3D project! Because the printer would failed as well. Thank you!!!

[MWard-kpdk]

Oh my god this was so quick and easy! My blender has somehow been reversing the faces and this helped so much, thank you. You saved multiple of my assets

[BoxBishop]

FINALLY! good quick tutorial explaining how to fix things instead of 20 minutes of offtopic about his pet or plant or whatever. thank you mate.

[ginho]

Saved my life. I actually wanted to go select individual faces to shift n, for a very complicated model. Thank you 😭

[NotLejam-]

Wow. For the whole year i've been using blender and sometimes getting this problem and now it's fixed on all my models. Thanks

Awesome guide.... thank you!
It does not only apply to 3D entities but also to STL export for 3D printing.
I used a cylinder as a starting point, removed the top and bottom faces and started edge loop offset extrusions to the outside, round to the top edge again, resulting in a torus with a special cross section profile. The exported STL still assumed that that initial cylinder wall was a solid to the inside, while in Blender edit I removed them.
Flipping those initial wall face normals was the key. Thanks again, for sharing this piece of insight.

Thankyou you have saved me so much time. I have been clicking on each indivual face and then Flip Normals. Doing it your way is far faster
