I’m making a prototype where my character and the whole level is placed inside a sphere mesh. Now i made the mesh double sided in order to have collision also from inside and into modeling (using UE 5.1) options i inverted normals so that i can see the sphere surface from the inside. The material for the sphere is also double sided. Now if i go outside of the sphere it’s outer surface turns invisible and i can only see it’s internal surface. How can i make visible both sides? I thought to make an hollow sphere in 3ds max using boolean compound object but i wonder if it cannot be done with a simple mesh!
Just take a normal sphere, and make the material two sided. Don’t invert the normals 
Ad i sayd the material is already two sided but it doesn’t work!
I tried it, no problemo…
That’s weird…i reloaded the project and now it works perfectly and i have touched nothing!
