Unwanted hollow texture on unity

[touzenesmy]

Hello guys, I'm making a new part and here it is:

When I export it to Unity, it becomes hollow, like the face toward me doesn't exist :/, same on ksp

here's the screen:

How can I make it to stop it from getting hollow ? it's like the part is textured inside, but not outside.

Your normals are off. You have to repair this in Blender

In the Edit/Object mode, edit window (right panel), under shanding, with multitexture set, there is a box called

[ ] backface culling

Click this and you and see the facings. Once this is set the faces that are suppose to be facing out on the surface will disappear.

Once you identify these on the right side panel select Shanding/UV under Normals, you can flip the direction.

It is a good idea to identify the mis-faced faces early in the construction process, because expanding mis-faces by

-Extruding

-Subdividing

-Duplicating

-Loop cut and slide

Will also duplicate the misdirections.

Thanks a LOT man !!

Didn't find right side panel select Shanding/UV under Normals but I did a "rotate" by 180° on each face at it worked

EDIT: didn't work well, googled flip normal, found it, and really, THANK YOU MAN
