unity backface culling removes outside of my walls with blender object
I am having problems with importing my .dae files into unity from blender.
At first some parts of my model weren't visible from the inside of my house due to backface culling. I have tried to flip those normals. This worked, however now the walls weren't visible from the outside of the house.
The next thing i've tried was extruding the wall and flipping just one side of the normals, though this caused the outer wall to be invisible and the inner wall to be visible in unity.
Is there any way to fix this properly or to disable backface culling in unity for certain parts of my model?
So i looked at your mesh, and its not well made!, you have a lot of overlapping edges, and i cleaned it up a bit. You also had backface culling turned on. disabled it, flipped a few normals and it works.

The normals were not flipped properly. You will need to reapply textures though. Backface culling, when done properly at source will not have to do it later in unity!.
You also need to learn how to properly create meshes without duplicate vertices or faces. As for How to disable backface culling in unity. From this thread it produces wrong lighting and have to replicate all the triangles with the script, so just stick to doing everything in blender it would be easier.
