Problem with "Textured Solid"-option

I have a 3D denture. The teeth are a canvas for brushes. In order to see the “brush strokes” in an animation-file I need to activate N-Shading: “Textured Solid”.

When I do this, then my other geometry in the file (the “gums”) suddenly misses many surfaces/triangles…How come??

I attach 2 screenshots illustrating the problem. I couldn’t upload the .blend here, so I put it into my dropbox: https://dl.dropbox.com/u/16029790/denture1.blend

Many thanks for your help!

I have seen now that all missing surfaces had the normal pointed into the opposite direction. When I flip the normal of such a triangle, then the triangle stays visible after switching on “Textured solid”.

  1. I guess its a about 500 surfaces I had to select and “flip”: is there any easier way to do this?

  2. I do not understand why switching on “Textured solid” for the denture influences the gums at all?? (there is no direct parent-child relationship between them. They are both childs of an other parent).

Ctrl+N recalculates the normals of selected faces. It is also best to remove any doubles befoe doing this (W / remove doubles)

Switching on Textured Solid changes the actual display of the 3d view not just the selected object
