Everything was appearing as normal as I was beginning to block out a corridor using BSPs (Geomtry box). I used the floor and duplicated it to build the walls; as you can see, both walls and the floor still exist in the scene - for some reason the bsp texture isn’t showing. Any help would be greatly appreciated. I have tried building the geometry, lighting etc, but what is causing the BSPs to not display? Have I accidentally hit a key combination? As a sidenote, I duplicated the BSPs in FRONT view, by using ALT+Middle mouse, then released. Is this correct method for duplicating?
This had me stumped for a while a bit back,
Click the show button in the viewport and enable BSP
Zoom out and check the layout.
