Make 3D objects unobstructed by other 3D objects

Question

I’m making a 3D first-person game,
and while I’m making 3D first-person items (flashlights, etc.),
I notice that I get a mold-through problem when the character is close to the wall.
I think it might need to be solved by a shader, but I didn’t found the content in my searches.
