Blender Importing Issues
Hello Everyone, I am new to blender and been having issues when I import my object it seems that only one side of it shows and when rotated the object disappears, Now I have heard that normals effects it so I try flip the normals and it does change which side shows now if I wanted the whole object to show.
For example if I wanted a can type object to where I create the cylinder in blender and delete the top face and import it, it has several issues but if i leave it how it is and import it, it shows the whole entire object
As you can see the one on left I removed the top face while the one on right hasn't been touched
Help would be appreciated thank you

The only option is to create an object with a "can in a can" which uses some more verticles. So the outside of the can would be like your left model, so you can see the sides, and your second one would be exactly the same, but with the normals flipped. and slightly scaled down.
Like this picture:
(this is a bledner object imported into unity)
Of course you need to create a face which connects the two sides (at the top and the bottom), so the can wouldn't have these ' gaps ' .
So your saying that since the normal can only appear on one side of the faces it makes the inside look like its missing and out side shows the object, so If I create a second mesh and have that normal flipped it should show like a can correct
That's right! faces can only be seen from one side, you'll look through them if you look from the wrong side. that's also why you can see through walls in some games.
