The backface of a mesh

Hi, i was wondering if someone could explain this topic to me.

As far as i understand it, a plane mesh is only visible on the side of the normals. but then how can i make a mesh plane that is visible on both sides?
according to all answers i have searched for, the solution is to use a 2 sided material, but this doesn’t feel right to me. what if i need a different material on each side?
does a two sided mesh doesn’t exist? can’t a mesh have 2 sides of normals? 2 different polygroups? or is that just the way a mesh is and the solution is either use a 2 sided material or make the mesh 3d instead of 2d?

thanks!

hi @LordPosix

There are some 3D programs that allow 2 sided meshes. They have 2 sets of faces on the same vertices just reversed order to generate the other side. Only issue I cam see with this Z fighting on the opposite side.

there is nothing wrong using 2 sided materials and im not sure how unreal would handle making 2 sided polys
