Flipping Normals on certain faces?

Hello Community

I have been working on a personal project for a friend. He as a game designer asked if I could make him a 32 sided dice with all of the letters and doubles for the vowels. I am going to 3D print these dice for him. I have the model and I made a texture in GIMP but here is were my question lies. I have done this but some of the faces are going out of the mesh instead of into it.


Desired Effect


Undesired effect

This is all flipped around for some of normals problem. What can I do?

  • Select all faces and Ctrl+A to recalculate normals. If your mesh has duplicate vertices or non manifold faces then this may not be 100% correct
  • Select faces and W / Flip Normals
