- A ceiling-only tile.
- An embrasure tile (arrow-slit), with a matching sunbeam, and a "view". Retexture the view with an appropriate screenshot, and place it just beyond the embrasure so the player can "look outside". The effect is quite impressive.
- Floor tiles. Each matches a standard tile, but is only the floor. Good for falsifying the in-game map: hide the real tiles under the in_lava_blacksquare, and construct a new, misleading map above that. Drives players CRAZY when the map doesn't match what they see!
- Three hidden doors. These will require scripting.
- A trap door that actually opens.
- A quarter pillar.
- An arched stained glass window. Will need retexturing.
- A round stained glass window. Will need retexturing.
- An arched imperial wall-only tile.
- Double-height impbig tiles, for buildling cathedrals.
- Double-width impbig tiles, for great halls.
All use existing vanilla Morrowind textures, except for the stained glass windows and the embrasure "view" - you'll have to provide your own textures for those.
