Can't find backface culling setting in version 2.78 I'm using version 2.78c and I just noticed I 'lost' the backface culling setting (I haven't used it in a little while). I can't post a screenshot of the shading area in the properties panel (blender render mode only), but the only check boxes available are: 


Textures 
Shadows 
Subsurface scattering 
Environment map
Ray tracing
World space shading (which is unchecked by default). 


There's also a drop-down for alpha, which I'm leaving at the default.

Every entry brought up in Google says 'Turn in on the in the shading area' - but it's not there and I can't find anything in user preferences that might control it's availability. Where has it moved to? I need to be able to check normals, and tasks like that.

Thanks in advance,
Frank Alviani
Press N key while in 3D View port (hover mouse there) and you will find Shading tab close to the bottom of this panel, which will show on the right side of the view port.



Edit:

Honestly I didn't ever paid attention that both of them panels are called 'Properties'.
