I’ve done an attempt on modeling a sign with a 3D Texr ‘404 Club’ on it.
This picture:
Now , ive tried to export it and im getting the picture bellow.
Anny ideas?
your normals are flipped.
And how do I fix that?
select the whole mesh in “Edit-mode” in blender press “T” and click “recalculate normals”. it is somewhere on the left side.
Thank you sir.
Have a nice night/day
the hotkey is ctrl+N, and if you hit N within blender the properties tab comes up (just like T with the tools tab). select your mesh when doing this and scroll down to the mesh display and there will be Normals select face and it will come up with blue lines coming from the mesh if they are facing in to the mesh the normals for that face needs to be flipped.
The first image is were you can find it, the second shows a normal thats not been flipped which you need and a normal which is flipped which you dont want, and the third is what you already know but showing you that you can select the face then flip or recalculate.
hope that helped.
