Speaking of game dev, why do I always have the same mising faces when I export my mesh for rigging? I went to all the trouble of learning how to do basic 3d modeling and texturing because I am so in love with my setting, and now I have an actual playermodel but I can't seem to fix this issue. What causes it? I swear to god I'm hitting select all
In blender I think shift+n in edit mode is the shortcut to flip your normals in the right direction. There should also be an option to show face normals with a little ray coming out in the direction they're facing. It's also worth doing a check for n-gons before you export (faces with 5 or more sides), and there should be an option to select faces by number of sides (thus highlighting any you miss), I forget where the option is off the top but it's there.
Is this from Blender? Blender by default shows both sides of a face, while most game engines hide the back face. So I'd guess that missing face might have its face orientation flipped compared to the others, and gets culled because of it.
oh damn, that's helpful as hell. thank you
