Generate Backface of a mesh in Blender

Question

I am using my blender objects in unity. Unity is culling the backfaces.

So I wanted to generate the backfaces as seperate polys from blender itself. I can do it by duplicating the mesh itself but is there any way to do it through a modifier?

Answer 1

The solidify modifier will generate a second surface parallel to the original.

If you want the new surface as a separate object, you can disable 'Fill Rim', then when you apply the modifier the mesh will be two disconnected parts. In edit mode Press L to select linked vertices which you can separate by selection P to move them to a second object.
