Hello, i have a model, and after i import it to Unity some faces are missing and it is not normals because in blender i pressed backface culling and it is still visible. Here are some images :

As you can see, the current face in red outline is clearly visible, also i have backface culling, believe me

And here, in the red outline the same place ,it is not visible, invisible, also, it is not just here, it is also in the random places over the mesh.Also as you can see, in the blue outline, the preview has no holes, it is a bit small so i don’t know if you can see it.

Also i uploaded the blend file here : https://drive.google.com/file/d/0B8323BCjcu4zR2hyd0lwRUt3ejg/view?usp=sharing (i couldn’t upload it anywhere else because of it’s size), as for the unity file, well just import the model into unity, and you will see. Please help, Thanks!

You can try exporting a fbx file and see if it’s the same there, unity under the hood is just calling blender to give it a fbx version of your blend file.
You can then import the fbx into blender to see if unity reads the fbx wrong (with i would doubt) or blender is producing a damaged fbx or your mesh with the default export properties cause an bug.
