The dunmer stronghold Exterior Tileset is pretty simple. The sub-tilesets are:
Base tiles
Fort tiles
Standalone Structures
Outer Wall tiles
(Freewall tiles)
(Extra rubble)
These function as the substructure of the stronghold. This sets your overall footprint, as all else will be on top of these.
There are no intended interior tiles to match these. A level designer may choose to create basements that progress into the space occupied by these.
These build the main structure on top of the stronghold base.
Inside of these is where the interior tileset will mainly play out, save for any basements that go into the substructure.
There are entryway tiles that will allow for entry at the ground level.
There is a specific entryway for entering/exiting the balconies.
Arrowslits are designed solely for placement on Forts.
There are three main standalone structures:
Propylon Chambers - must have one per stronghold (save for special cases), and have a unique taller entryway (02)
Dome - should be used sparingly, not more than one or two per stronghold; can also be used as the entry/exit point for the tops of Forts. There are small windows that can be placed on the upper-most stone wall section
Dwelling - can be used however many times; can also be used as the entry/exit point for the tops of Forts. there are small windows that can be placed on the upper-most stone wall section
There is also a large ashpit, multiple of which usually appear on top of fort structures.
These are intended to snap to the edges of the Base tiles. They are defensive walls.
They can also have Forts nested behind them (will not snap, must do so by hand).
There exists a gate tile that will fit the dunmer stronghold gate. Intact gates should be used sparingly. There are also ruined variants of the gate.
Extras:
There are larger rubble piles for exterior use (reusing some exterior parts).
There are freewalls and free blocks.
There are ruined variants for almost all tiles.
The dunmer stronghold Interior Tileset is mostly simple, but comes with some caveats. The sub-tilesets are:
Large Room tiles (to include Balconies, Bridges, and Platforms)
Large Hall tiles
Small Room tiles
Small Hall tiles
Perimeter Hall tiles
Standalone Structures
(Freewall tiles)
(Extra rubble)
These will probably be used for one main room in the stronghold. They are intended to fit within exterior Fort tiles.
These are broken into top and bottom halves, for maximized 3D efficiency (less tile permutations).
There are various pillars that snap to the top half and bottom half walls, as well as pillars that stretch the height of the room.
When snapping other sub-tilesets to the top-half entryways, be aware that the distances between floors here is 416 units. It is recommended to use a Snap To Grid setting of 32 or 16 to ensure that you can snap floors together properly.
These include Balconies, Bridges, and Platforms and are intended to augment your Large Rooms to be more interesting.
Balconies:
Snap to the top halves of Large Rooms.
Requires a bottom half Large Room tile.
Can transition into Platforms.
Can transition into Bridges.
Bridges:
Always requires a Balcony or Platform transition tile.
There is also a pillar that is specifically designed to fit under the height of the Bridges.
Platforms:
Snap to the top halves of Large Rooms.
Does not require a bottom half Large Room tile.
Can transition into Balconies.
Can transition into Bridges.
There are also several staircase Platform tiles that can bridge the gap between the top half and bottom half of the Large Rooms.
These are a double-wide hallway type, intended for moving between Large/Small Rooms.
They have one interface type, that being the Large Door Interface.
There is a hallway-wide pillar and a couple sconce variants for lights/candles.
These are simple, nothing crazy.
There are two variants of these: A + B. There is some variation in the walls and ceiling and have no wider intention.
There are a couple pillar variants.
These are a more claustrophobic hallway type, intended for moving between Large/Small Rooms, and for connecting to Perimeter Halls.
These are also intended as the main mode of connection between different floors, as this is the only sub-tileset (save for Large Rooms) with staircases.
There are 5 different staircases, each with different heights for different purposes, largely intended to help match heights with the exterior but also for snapping to top half Large Room tiles.
Two that are 416 units tall - Large Room top half floor height
One is 256 units tall - reaches arrowslits on 2nd exterior vertical partition
One is 160 units tall - for bridging gap between the prior and the Large Room top half
One is 96 units tall - reaches exterior balconies
Because these can reach the 2nd exterior vertical partition, there is an interior arrowslit station and shutter for the Small Hall tiles.
These are intended to be used at the ground level of the exterior Fort tiles. They run the entire perimeter of the Fort.
These halls have a slanted side and a flat side. The slanted side must face the exterior, while the flat side faces the interior.
There are two variants of these: A + B. There is some variation in the ceiling and have no wider intention.
Because these run the perimeter of the exterior Forts, there are entrance tiles for where the exterior entryways will sit along the exterior Fort walls. These also only interface with other sub-tileset from the flat side.
Because these face the exterior, there is also an arrowslit station and shutter for the Perimeter Hall tiles.
There are three standalone structures that correspond to the three exterior standalone structures:
Propylon Chambers - WIP
Dome - the exterior window asset doubles as an interior side of the window
Dwelling - the exterior window asset doubles as an interior side of the window
There are smaller rubble piles for INT and EXT use (reusing some interior parts).
There are freewalls and freepillars.
