so I have a problem with exporting. I finally have gotten myself to pick up Blender and this is my first attempt at a low poly model created from the ground up. And in blender it seems to render just fine

This is my Blender working field

But once I export the image, and open it up into unity to see how that renders it, there seem to be holes in it and stuff rendered inside out (just an observation?)

This is my problem with Unity

Can anybody help me suggesting how to fix this problem?

Including the blender file

Unity does Backface culling by default whereas Blender only does it on request. The issue is that the normals are flipped. If you want to turn on Backface culling in Blender it is in the Properties panel.

Here I have removed a face from the default cube. enter image description here

and now with Backface culling enabled. enter image description here

You can see through the faces that are facing outwards. To fix this, i.e. making a room, you can flip the normals so the faces face inwards.
