Ive recently got back into playing 1 and added a couple mods NW shader and the camera mod. I thought i read somewhere a little while back that added ceilings,but now cannot find anything about it.
Any help?

I'm afraid you've been misinformed. There are ceiling hacks for some tilesets, and there are some placable "ceilings" built into the CEP, but there's nothing built into the shader or camera mods.
