Hello. I really need your help!! (I’m a university student)
(I’m not good at english so my sentences can be not correct…)
I made a house(I followed one video on youtube) and imported it to unreal engine.
When I try to see the walls through a door, I can’t see them. They are gone.
And when my character goes inside the house, there’s no wall.
I can see the walls outside of my house but I can’t see them through the door.
Thanks for reading this question and I’ll waiting for your answers. Thank you:)
