How do i make a double face plane? in blender 2.8

when I export it to unreal it has some invisible faces

You'd have to have faces on both sides when you export it out from blender. Multiple ways you might do this. You could use a solidify modifier I believe. You could duplicate your faces, scale them in slightly, and then recalculate the normals to be pointing inwards. Depends on what you are making I guess, you just need to have another face pointing inwards for whatever you can see through.

Or, if you have a solid mesh that doesn't have anything that requires a double sided face you might just have to recalculate some of the normals on your mesh.

Also if these are outside faces that are invisible, you may have flipped normals when you were creating the model, (especially if you use the old duplicate SX-1 (Scale X Minus 1)) routine to flip duplicated mesh to the other side of the X axis.

Select the entire model and place it into Edit mode then run Ctrl+N and recalculate the normals to the outside.

If the edges of the model are not non manifold this should fix the problem of invisible outside faces.

just enable the TwoSided option of the material properties in ue4 bruh
