How can I make REALLY REALISTIC stone tunnels for the game engine? I would have just gone for “Theeth’s Quick Blender Tutes” on “Holes,” but they’re all gone.
I’m making an adventure game, and I want the player to go through a tunnel through a mountain.
Mmmm…
REALLY REALISTIC and FOR THE GAME ENGINE doesn’t match 
Personally I would take a cube
Disintegrate two (opposite) faces just to make a kinda short tunnel
Extrude one end many times keeping new faces square.
Select all vertices
Press ‘Fract subdivide’ twice.
THis will make a nice rought yet low poly tunnel.
Bend it via a lattice or something else
Apply a cool stone texture.
Et voilà
