UO Renaissance objects (statics and items)

The catalog of world objects to bake as sprites: housing pieces, furniture, lights, crafting stations, decoration, dungeon and civic props, nature, and items lying on the ground. It covers what a player saw in Britannia around the Renaissance release (2000): pre-made houses and keeps, towns, dungeons, the Lost Lands. It is our own modelling of those object types (no UO art is used). The ground terrain is in uo-base-tiles.md.

Every object is a procedural Blender script baked by uo-baker (format: sprite-format.md, pipeline: asset-pipeline.md). Each group owns a manifest file assets/manifest.d/<group>.toml and a script folder tools/blender/models/<group>/; shared helpers are in tools/blender/models/object_kit.py. Review with python3 tools/gallery.py --group assets/manifest.d/<group>.toml -o sheet.png.

Conventions

• Scale (1 unit = 1 tile): human 1.8, wall 2.12 (48 px storey), door 1.89 (42 px), chair seat 0.45 / back 1.0, table top 0.77 (level 17), counter 1.0 (level 22), bed top 0.5, bookcase/armoire 2.0, barrel 0.9, chest 0.5, candle 0.15.
• Facings: objects with a front bake directions = 4 (frames North, East, South, West; the model is built facing south, −Y). UO had separate art per facing; the client picks the frame. Wall-mounted items (paintings, sconces, shelves) are built against the north edge facing south: the South frame hangs on a north (x) wall, the East frame on a west (y) wall.
• Walls and fences follow the wall convention (decision #16, #22): a piece sits inside its tile, flush with the north edge (_x, runs east–west) or the west edge (_y), corners/posts at the north-west corner; origin at the tile centre.
• Multi-tile objects: origin at the centre of the north-west-most tile, the object extends east (+X) and south (−Y); manifest footprint = [w, h]. Multi-tile objects with a front (marked 4 below with a footprint) are baked as two assets instead of four facings, <name>_s and <name>_e (front south / east, footprints [w, h] / [h, w]), as UO did.
• Pixel art: every model sits on the texel lattice (pixel_kit.py, decision #60, rules in docs/asset-pipeline.md). Silhouettes bold, details whole texels, colour contrast over fine geometry; muted, warm UO palette (object_kit.PALETTE).

Legend: 4 = 4 facings; WxH = footprint; p: = one script, assets selected by params.

Wave 1

walls — housing wall sets (wall_<material>_<piece>)

One script per material (tools/blender/models/walls/wallset_<material>.py), the piece picked by params = { piece = "..." }. Pieces: x, y, corner, post, window_x, window_y, doorway_x, doorway_y (doorway = opening for a door sprite, 12 texels wide × 42 levels high). Height 48 levels (one storey, 2.12 units), 2 texels thick.

The full sets (all but cave and palisade) also have the pieces the building generator (crates/uo-buildings, #101) orders in assets/requests/wall-pieces.md, built by walls_kit from each set's own wall and post code (decision #102):

• diag_a (/, north-east to south-west: a camera-facing horizontal run) and diag_b (\, edge-on), plus _window variants: full height, run between the corner posts of the wall grid (1 texel inside the north and west tile edges), so they meet the straight walls and posts of a cut corner exactly; the frame is sheared (2 texels thick along Y, ends on X planes), so it stays on the lattice and joins the next diagonal tile. Window u -3..3 (8.5 texels along the slant). They block their tile, no edge. Their outlines sit on half-pixel rows and stay softer than straight walls.
• low_x, low_y, low_corner, low_post: parapets of balconies and terraces, the set's wall cut at level 16 under a 2-level coping (posts cap one level higher).
• slit_x, slit_y: an arrow slit 2 texels wide at levels 22..36 through the back half of the wall, splayed one texel and one level on the front half.
• crenel_x, crenel_y, crenel_corner, crenel_post: tower-top parapets, solid to 10 under a string course to 12, merlons 12..22 capped to 24, 4 texels merlon and 4 gap (x runs at u -8..-4 and 0..4, y runs mirrored), so both runs have a merlon at the north-west corner and the corner piece an L-shaped corner merlon; posts are merlons.

nature — trees, plants, rocks

Trees, bushes, shrubs, ferns, tall grass, flowers, mushrooms and the single rocks are built from the Quaternius CC0 nature packs (decision #74): tools/blender/models/nature/packs.py imports the converted models in assets/models/nature/ (one pack model per variant, the client picks one per tile), scales them to real size (1 unit = 1 m: grown trees 10-17 m, apple 6.5-8, sapling 3.5-4.5), cuts them at the ground and recolours the leaf cards per species. tree_willow adds hanging leaf-card curtains to a pack crown. rocks (cluster), mushroom_giant, cacti, reeds, vines, lily pads, stump and logs stay procedural (plants.py, rocks.py; the procedural trees.py is retired). Trees keep footprint = [1, 1] (the trunk's tile). Every tree with leaves (all but tree_dead) has bare = true: its bare twin in bare/ is the same variant without leaves and fruit, which the client shows while the crown is hidden near the player (decision #98).

roofs_stairs_floors

Roofs roof_<material>_<piece> (p: material ∈ slate, thatch, shingle, tile; piece ∈ slope_s, slope_n, slope_e, slope_w, ridge_x, ridge_y, corner_se, corner_sw, corner_ne, corner_nw). Roof contract: a piece's base is at Z = 0 and the client places it at wall height; slopes rise 32 levels across a tile (ROOF_COURSE = 32 px ≈ 1.41, a 55° pitch, so course edges draw as 1:1 lines or verticals; slope_s low on the south edge), so each further course of roof tiles sits 32 px higher; the roof script takes rise for other pitches. Stairs stairs_<material>_<piece> (p: wood, stone; step_s, step_e, block; one tile rises 12 levels, four tiles = one 48-level storey); floors floor_<material> (stone, marble, marble_checker, wood_light, wood_dark, sandstone, brick, carpet_red, carpet_blue, carpet_gold).

In the client

The client places objects as uo_proto::objects::StaticObjects (sprite, tile, absolute z, facing) on a static layer of impostors; see docs/rendering.md › Static objects.

Demo village

The offline demo (crates/uo-client/src/village.rs) is a village of 90 x 56 tiles in the middle of a 128 x 128 map that places every object of the catalog (a test checks it against assets/manifest.d; 2222 statics of 484 sprites):

Building	Walls	Storeys, roof	Inside
player's home	stone	1, slate	table set for dinner, fireplace, bed, bookcase; secret back doors
tavern	wood	2, shingle (ridge)	bar with kegs and bottles, tables, musicians; inn rooms above
mage tower	marble	3, tile (ridge)	alchemy lab, study with books and globe, archmage's hall with throne
weaver	plaster	2, thatch (ridge)	loom, spinning wheel, dye tub, dress form; bedroom above
bakery	brick	1, tile (ridge)	ovens, flour mill, sacks, bread and pies
gaol	dungeon	1, slate (ridge)	barred doors, chains, iron maiden, traps, lever
smithy	fieldstone	1, slate	large forge, anvil, armour, ingots; metal doors
provisioner	sandstone	2, shingle (ridge)	counter with scales and coins, display case; strongroom above
hunter's cabin	log	1, thatch (ridge)	fireplace, furs, bedroll, bows; open doorways
stockade	palisade	—	training dummies, archery range (rope fence), tents, camp
mine	cave	—	rails, mine cart, crystals, stalagmites, giant mushroom

Around them: cobbled streets and a flagstone plaza (fountain, well, statues, market stalls, bell, a seasonal corner), a justice square (gallows, stocks, guillotine, gibbet), a mage garden behind a hedge (pentagram, moongates, shrines, teleporter), a graveyard behind a wrought-iron fence, a paddock (split rail), a vegetable patch (pickets), a farm field (dry-stone wall), a desert garden, an orchard, a pond with a dock and, in the south-east, a mason's yard with one exhibit per full wall set (crenellated and low corners with their posts, a \ and a / diagonal run, slits in an x and a y wall). All 28 doors, 8 gates, 6 fence and 11 wall sets, 40 roof pieces (ridges come from roofs with an odd short side), 6 stair pieces and 10 floors are used.

• Storeys: storey s stands at z + WALL_HEIGHT · s (48 px each); its floor covers the interior except the stairwell of the flight from below. A flight is four stair tiles (step_s climbing north or step_e climbing west) rising 12 px each, with stairs_*_block pieces stacked under the higher steps; the top step ends level with the next floor.
• Wall rings: corner piece on the north-west tile, _x along the north and south rows, _y along the west and east columns, posts at the other three corners; a window on every wall tile whose offset along the wall is 2 mod 3; doorway pieces (with a door, or open) where the plan says. Fences use the same ring with gates replacing pieces.
• Roofs: uo_proto::objects::hip_roof(material, x, y, w, h, z) gives every tile of a w x h building the piece of its nearest outer edges (slopes, hip corners, ridges), one course (+1.0) higher per tile inwards, eaves at the top storey's wall height. With an even short side the roof is a clean hip without ridge pieces; with an odd short side a ridge runs along the middle row (or column) and its end tiles, where three slopes would meet and the set has no piece, leave a small gable. The village uses both. Roofs and upper storeys hide while the player is inside (UO style).
• Lights: objects with glowing texels (candles, sconces, braziers, fireplaces, lamp posts, campfires, moongates, crystals) get a point light at their flame automatically; walls (glowing window panes) don't.

Follow-ups

• Open doors swing into the tile they stand on (south for _x, east for _y), so a door in a building's south or east wall opens outwards. Doors opening the other way need a second open state (e.g. open_out).
• The south and east walls stand just outside the roof's tiles (walls sit on the north/west edge of their tile), so their tops show a 0.09-unit ledge below the eaves on the camera side. A roof edge piece or a wider eave overhang on the south and east would hide it.
• A hip-end piece (three slopes) would allow hip roofs with an odd short side; gable-end wall pieces would allow gable roofs.
• Players can't climb stairs yet (walking is 2D on the terrain), so upper storeys are only seen, not visited; RoofView decides what is drawn.
• Statics are client-side only (the demo builds them); the server still has to own and send them (a statics list in Welcome or per region), and multi-tile blocking should come from the manifest footprint.
• Seasonal or rare variants of statics (e.g. cave walls) could use variants = N like the ground tiles; the client already picks a variant per tile for such sheets.
